1. Light is an electromagnetic wave that vibrates perpendicular to its direction of propagation, making it a transverse wave.
2. Mirrors reflect light via the law of reflection, where the angle of incidence equals the angle of reflection. Plane mirrors form virtual upright images of the same size as the object, while curved mirrors can focus light.
3. Lenses refract light to form real or virtual images. Convex lenses are convergent, collecting light rays and forming an upright magnified image. Concave lenses are divergent.
1) Light reflects off surfaces according to the laws of reflection - the incident ray, normal, and reflected ray all lie in the same plane and the angle of incidence equals the angle of reflection.
2) Plane mirrors form virtual, upright images that are the same distance behind the mirror as the object is in front. Concave mirrors can form real or virtual images, depending on the position of the object.
3) Convex mirrors always form smaller, virtual, and upright images of objects and are commonly used in automotive rear-view mirrors and security mirrors.
When waves interact with matter, they can be reflected, transmitted, or a combination of both. Reflection is when waves bounce back into the original medium, obeying the law of reflection where the angle of incidence equals the angle of reflection. Refraction occurs when a wave changes speed upon crossing a boundary between media, causing it to bend. Both light and sound waves undergo reflection and refraction, which can make objects appear in different locations than they actually are due to the bending of wave fronts.

This document provides an overview of geometric optics, including reflection, mirrors, refraction, and lenses. It discusses how light rays reflect off mirrors according to the law of reflection, forming real images with plane mirrors and virtual images with spherical mirrors, whether concave or convex. Concave mirrors bring parallel rays to a focus at their focal point, while convex mirrors cause parallel rays to appear to diverge from a virtual focal point.

- Reflection of light occurs when light bounces off a surface. The angle of incidence is equal to the angle of reflection.
- Refraction occurs when light changes speed and direction as it passes from one medium to another. The ratio of the sines of the angles of incidence and refraction is a constant value called the refractive index.
- Experiments can show that light reflects according to the law of reflection and refracts at different angles depending on the medium, such as when passing through glass blocks. Measurements are used to determine refractive indices.
Optics is the study of light, including its interactions with mirrors, lenses and other objects. When light strikes an object it can be reflected, transmitted, scattered or absorbed. Mirrors come in three types - plane, concave and convex. Plane mirrors reflect light at the same angle it is received. Concave mirrors curve inward and can form real or virtual images, while convex mirrors curve outward and always form virtual images. Lenses also come in concave and convex forms, with convex lenses able to form real or virtual images depending on the object position. Optical instruments like telescopes, microscopes and cameras use lenses and mirrors to collect, focus and magnify light and images.

This document discusses the basics of mirrors and reflection. It explains that a simple mirror is made of a plane glass with a silver coating on the back protected by a layer of red paint. This allows the glass to provide a smooth reflective surface while preventing light from passing through. The key points of reflection are also outlined, including how the incident ray strikes the mirror at the point of incidence, and the reflected ray bounces off at the same angle following the law of reflection.
Light is a form of energy that allows us to see objects. When light reflects off objects and enters our eyes, we see the objects. There are two main types of reflection: irregular/diffused reflection which scatters light in all directions for general illumination, and regular/specular reflection which forms images using smooth, shiny surfaces like mirrors. Spherical mirrors can be either concave which converge light to a focal point, or convex which diverge light appearing to come from a point behind the mirror. The mirror formula relates the object and image distances to the focal length. Concave mirrors are used in flashlights and car headlights while convex mirrors are used as rear view mirrors in vehicles.
Light is an electromagnetic wave that can be reflected, absorbed, or refracted. The law of reflection states that the angle of incidence equals the angle of reflection. Mirrors can form either real or virtual images. Concave mirrors focus parallel light rays to a focal point, forming real, inverted, and reduced images between the focal point and center of curvature. The mirror equation and magnification equation can be used to calculate the location and characteristics of an image formed by a spherical mirror.

Voltaic cells were an early form of battery invented by Alessandro Volta in the late 18th century. A voltaic cell consists of two different metal plates, such as zinc and copper, placed in contact with an electrolytic solution, such as sulfuric acid. When the plates are connected by a wire, electrons will flow from the zinc (the anode) through the wire to the copper (the cathode), generating a small electric current that can power a lamp for a short time until polarization occurs due to hydrogen gas bubbles forming on the copper plate and blocking the current flow.

This document summarizes key points from Thomas Friedman's book "The World is Flat" which discusses the impact of globalization in the 21st century. The book analyzes 10 factors, referred to as "flatteners", that have allowed the world to become more interconnected. These include the fall of the Berlin Wall, the rise of workflow software and the internet, outsourcing and offshoring, and new technologies like smartphones that have accelerated global collaboration and competition.
The document discusses the history and workings of the voltaic cell, which was an early battery invented by Alessandro Volta in the late 1700s. It describes how Voltaic cells consist of a glass jar containing sulfuric acid solution, with a zinc plate serving as the anode and a copper plate as the cathode. When the copper and zinc plates are connected by a wire through a small lamp, the lamp will turn on as electric current flows. However, the lamp only remains lit briefly before dimming out due to a process called polarization, where hydrogen gas bubbles form on the copper plate and disrupt the electric current.

The document discusses the history and workings of the voltaic cell, which was an early battery invented by Alessandro Volta in the late 1700s. It describes how Voltaic cells consisted of zinc and copper plates submerged in an acidic electrolyte solution, which produced a sustained electric current to power small devices like lamps. However, the cells suffered from polarization over time as hydrogen gas bubbles formed on the copper plate and disrupted the current flow, causing the lamps to dim and turn off until the bubbles were cleaned away.
There are two types of mirrors: plane and curved. Plane mirrors form virtual, upright images of equal size to the object. Curved mirrors can be concave or convex. Concave mirrors converge parallel rays to a focal point, forming real or virtual images that can be upright or inverted and enlarged or reduced. Convex mirrors diverge rays and always form smaller, upright, virtual images. Refraction is the bending of light when passing from one medium to another, causing image formation in lenses and the eyes.
This document provides an introduction to geometric optics. It defines optics as the science of light, discussing properties of light such as its speed and travel in straight lines. Geometric optics examines light behavior using a ray model, where light travels in straight lines. It discusses types of optical devices like mirrors and lenses, which can reflect or refract light to control its path. Mirrors are described as either plane, concave, or convex based on curvature, and produce real or virtual images depending on geometry. Lenses are also concave or convex and refract light toward their thickest point. The document demonstrates optical principles like image formation using ray tracing diagrams for different mirror and lens configurations.

Light is a form of energy that allows for vision. It travels in straight lines and can form shadows. Advanced light detection technology can detect single photons, measure light from the universe, and track fast processes in living cells down to billionths of a second. Concave mirrors are used in telescopes to focus faint light from space, while convex mirrors give a wider field of vision useful for security and vehicles. Reflection occurs when light bounces off a surface, either diffusely scattering in all directions from a rough surface or specularly at the same angle from a smooth surface like glass or metal.
Lens and Mirrors [Autosaved] for Grade 10.pptxMaamKatrynTan
This document discusses the anatomy and properties of lenses and mirrors. It defines key terms like focal point, principal axis, radius of curvature, and types of lenses and mirrors. Ray diagrams are demonstrated as a technique for determining the characteristics of images formed by concave and convex mirrors and converging and diverging lenses based on the position of objects. Reflection and refraction principles are reviewed for understanding image formation.
This document discusses different properties and behaviors of light, including reflection, refraction, and detection methods. It explains that light is a form of energy that allows for vision. Advanced cameras can now detect single photons and measure ultrafast light changes. Concave mirrors are used in reflecting telescopes to view distant objects, while convex mirrors provide wider views for security and vehicles. Reflection occurs when light bounces off a surface, either diffusely from rough surfaces or specularly from smooth surfaces at the same angle. Refraction is the change in light's direction when passing from one medium to another, governed by Snell's law.
When light travelling in one medium falls on the surface of second medium the following three effect may occur.
1:- A part of incident light is reflected back into the same medium. This is called Reflection of light.
2:- A part of light is passes through the medium.This Is known as Refraction of light.
3:- And remaining part of the light is absorbed by the surface on which the light fall. This is known as Absorption of light.
The document provides an introduction to the physics of mirrors. It discusses how flat mirrors form virtual images that are upright, the same size, and located behind the mirror. Curved mirrors like concave mirrors bring parallel rays of light to a focus at a focal point a given focal length from the mirror's center, while convex mirrors cause parallel rays to appear to diverge from a virtual focal point behind the mirror.
1) The document is an introduction to the physics of mirrors, covering the basics of reflection, flat mirrors, spherical mirrors, focal length, and concave and convex mirrors.
2) Flat mirrors form virtual upright images that are the same size and located the same distance behind the mirror.
3) Concave mirrors bend rays toward the principal axis such that parallel rays converge at a focal point a distance f=R/2 in front of the mirror. Convex mirrors bend rays away from the principal axis such that rays appear to diverge from a focal point a distance f=-R/2 behind the mirror.
1) Light travels as waves and can be reflected, refracted, or absorbed when it interacts with matter. It is part of the electromagnetic spectrum and travels extremely fast.
2) Mirrors reflect light following the law of reflection, forming virtual images. Plane, convex, and concave mirrors have different shapes and uses.
3) Refraction occurs when light changes speed as it passes from one medium to another, causing it to bend. Refraction through lenses forms real images and enables vision corrections and camera lenses.

3. Light is an electromagnet wave, namely the wave the vibration of which is electric field and magnetic field. Because the direction of vibration of the field and magnetic field are perpendicular to its spreading direction then light is included into TRANSVERSE WAVE DEFINITION AND PROPERTIES OF LIGHT
4. 1) Spreading According To Straight Line For example : in dark room is made a little slit so sunlight can enter. Sunlight that enters will be seen spreading according to straight line. PROPERTIES OF LIGHT
5. 2) Has Energy Light has energy, such as sunlight which is used to dry clothes. That shows light contains heat energy.
6. 3) Can be Seen The light radiates from light source, such as sun, flash light, candle, and so on can be seen by our eyes.
7. 4) Radiated in the Form of Radiation light is an electromagnetic wave that is radiated in the form of radiation. Radiation is energy emitted from a source in the form of rays or waves.
8. 5) Has Spreading Direction Perpendicular to Vibration Direction As wave, light is included into transverse wave, which is spreading direction is perpendicular to the direction of vibration.
9. 6) Can Experience Reflection, Refraction, Interference, Diffraction, And Polarization In everyday life, when the night comes we cannot see the things around us without the aid of the light, such as moonlight, or lamp. Means there are things that can radiate light their self and there are also things that cannot radiate light their self. Their bodies that can radiate light is called light source. Example: sun. The bodies that cannot radiate light their self is called dark body. Example: stone, wood, planets, and so on
10. Dark body if gets light can be separated into 3 kinds, namely: Opaque body, namely a dark body that does not continue at all the light it receive. FOR EXAMPLE: carton, book, and wood. Transparent body, namely dark body that continue a part of light it receive. FOR EXAMPLE: thin paper Clear body, namely dark body that continue almost all light it receive. FOR EXAMPLE: clear glass. DARK BODY
11. The image formed from a body is divided into two kinds, those are Umbra and Penumbra. Umbra is the region that doesn't receive light at all so appears dark. Penumbra is the region that receive a part of light so appears vague. UMBRA AND PENUMBRA
14. From the figure in the above, ray from the flash light in the box to mirror is called incident ray. Flat mirror has function as reflection plane and the ray reflected from the mirror is called reflected ray. Incident angle is the angle formed by incident ray and normal line. Reflected angle r is angle formed by reflected ray and normal line. By the activity above is obtained the following conclusion: Incident angle, normal line and reflected ray lie on one flat plane. Incident angle is equal to reflected angle (i= r)
15. Reflection happens if the stream of light falls on the body that its surface is smooth and shiny, so direction of the light reflection goes to certain direction. In everyday life the specular reflection can be observed in light reflection by mirror and shiny metal surface. The Kinds of Light Reflection
16. If the light falls on the rough surface (not flat), then the stream of light will be reflected to every direction irregularly. This irregular light is called diffuse reflection. So, the diffuse reflection happens if the stream of light falls on the body which its surface is rough (not flat), so the stream of parallel rays which fall on the body will be reflected to every direction.
18. A flat mirror is the glass the surface of which is flat and one of its surface is covered with silver metal. In every day life the mirror that we usually use to make up is the flat mirror Light Reflection on Flat Mirror
19. Beside flat mirror there is also another mirror that can reflected light, namely concave mirror. Concave mirror is a mirror the surface of which is shiny and curves inward like slice of ball that is inner part is shiny. Light Reflection in Concave Mirror
20. Light reflection in the concave mirror some have particular properties depend on the incoming of the light. There are three particular rays in the concave mirror. Incident ray which is parallel to main axis of the mirror will be reflected passing through the focus point F. The incident ray passing through the focus point F will reflected parallel to main axis. The incident ray passing through center point of mirror C will be reflected back through that center point of curvature.
24. Convex mirror is inverse of concave mirror. In convex mirror the shiny surface lies is outer part of ball slice. So the surface that reflect light curves outward. Light Reflection in Convex Mirror
25. Same with the concave mirror, the convex mirror also has particular rays, namely: The Incident ray parallel to main axis is reflected seemed comes from focus point of the mirror (F). Incident ray to focus point (F) is reflected parallel to main axis. Incident ray to center of curvature of mirror C is reflected back seemed comes from the center point of curvature (on the same line).
30. Mirror A mirror is an object with at least one polished and therefore reflective surface. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected image.
31. Mirror Mirrors are commonly used for personal grooming (in which case the old-fashioned term "looking-glass" can be used), decoration, and architecture. Mirrors are also used in scientific apparatus such as telescopes and lasers, cameras, and industrial machinery. Most mirrors are designed for visible light; however, mirrors designed for other types of waves or other wavelengths of electromagnetic radiation are also used, especially in optical instruments.
32. Effect In a plane mirror, a parallel beam of light changes its direction as a whole, while still remaining parallel; the images formed by a plane mirror are virtual images, of the same size as the original object (see mirror image). There are also concave mirrors, where a parallel beam of light becomes a convergent beam, whose rays intersect in the focus of the mirror. Lastly, there are convex mirrors, where a parallel beam becomes divergent, with the rays appearing to diverge from a common intersection "behind" the mirror.
33. Effect Spherical concave and convex mirrors do not focus parallel rays to a single point due to spherical aberration. However, the ideal of focusing to a point is a commonly-used approximation. Parabolic reflectors resolve this, allowing incoming parallel rays (for example, light from a distant star) to be focused to a small spot; almost an ideal point. Parabolic reflectors are not suitable for imaging nearby objects because the light rays are not parallel.
34. Applications Safety and easier viewing: Rear-view mirrors are widely used in and on vehicles (such as automobiles, or bicycles), to allow drivers to see other vehicles coming up behind them. Two-way mirrors : A two-way mirror, also sometimes referred to as a one-way mirror or one-way glass, reflects some percentage of the light and lets some other percentage pass. It is a sheet of glass coated with a layer of metal only a few dozen atoms thick, allowing some of the light through the surface (from both sides). It is used between a dark room and a brightly lit room. Signalling: With the sun as light source, a mirror can be used to signal by variations in the orientation of the mirror. The signal can be used over long distances, possibly up to 60 kilometres on a clear day.
51. Active mirrors are mirrors that amplify the light they reflect. They are used to make disk lasers.
52. An atomic mirror is a device which reflects matter waves. Usually, atomic mirrors work at grazing incidence.
53. Cold mirrors are dielectric mirrors that reflect the entire visible light spectrum while efficiently transmitting infrared wavelengths.
54. Corner reflectors use three flat mirrors to reflect light back towards its source. They are used for emergency location, and even laser ranging to the Moon.
55. X-ray mirrors produce specular reflection of X-rays. All known types work only at angles near grazing incidence, and only a small fraction of the rays are reflected.

59. Convex mirrors are used in some automated teller machines as a simple and handy security feature, allowing the users to see what is happening behind them. Similar devices are sold to be attached to ordinary computer monitors.
60. Camera phones use convex mirrors to allow the user correctly aim the camera while taking a self-portrait.

62. Pictures of Convex Mirror Convex mirror lets motorists see around a corner.
63. Concave Mirror A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point, therefore they are used to focus light. Unlike convex mirrors, concave mirrors show different types of image depending on the distance between the object and the mirror itself. These mirrors are called "converging" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles, since the normal to the surface differs with each spot on the mirror.

67. Mirror Writing Mirror writing is formed by writing in the direction that is the reverse of the natural way for a given language, such that the result is the mirror image of normal writing: it appears normal when it is reflected in a mirror.
68. Pictures Eighteenth century mirror writing in Ottoman calligraphy. Depicts the phrase 'Ali is the vicegerent of God' in both directions.
78. Lens Lens is transparent material that bordered with two bending planes Lens will refract the light that come from object (Light behind object) and make virtual or real image of object
79. Types of Lens There are two basic types of lens in the world (that I know), those are convex lens and concave lens Convex lens has thinnest part in its side, while concave lens has thinnest part in its center
80. Part of Lens Part of convex lens are: Focus point (Principal and virtual focus) Principal axis Lens Curvature Optical Center
84. The Image (Part 1) This is some examples of images that are formed by a convex lens By using particular ray of convex lens, we can get... Images beyond P2 ...(Room III) P1 F2 F1 P2 Real Image
85. The Image (Part 2) If the object between P2 and F2 (Room II)... The images is... P1 F2 F1 P2
86. The Image (Part 4) If the object between O and F2... (Room I) P1 F2 F1 P2 The images is virtual images...
87. Concave Lens There is one again lens, concave lens Concave Lens has thinnest part in its center
88.
89.
90. Special Ray (Particular Ray) A ray parallel to principal axis is refracted like from active focus point F1 A ray toward F2 is refracted parallel to principal axis A ray through optical center is not refracted
93. The Image This is some examples of images that are formed by a concave lens By using particular ray of concave lens, we can get... P2 F2 F1 P1
94. The Image How if the object is located between F1 and P2? Images that are formed is same! So, we get summary if concave lens always makes virtual, upright, and minimized image. P2 F2 F1 P1
95. Function of Lens There are many function of lenses. With lens, we can make optical object, like magnifying glass, eyeglasses, microscope, and others
96. Count It! In lens, there is also relationship between focus distance, object distance, and image distance. The formula is same with mirror = Focus distance (m) = Object distance to lens (m) = Image distance to lens (m)
97. Count It! Beside focus, object distance, and image distance, we can calculate magnification and height of object and image. = Magnification = Height of image = Height of object = Object distance to lens = Image distance to lens
100. OPTIC TOOLS Optics is the study of the behaviour and properties of light including its interactions with matter and its detection by instruments. The word optics comes from ὀπτική, meaning appearance or look in ancient Greek.
101. Optics usually describes the behavior of visible, infrared, and ultraviolet light; however because light is an electromagnetic wave, similar phenomena occur in X-rays, microwaves, radio waves, and other forms of electromagnetic radiation and analogous phenomena occur with charged particle beams. Since the discovery by James Clerk Maxwell that light is electromagnetic radiation, optics has largely been regarded in theoretical physics as a sub-field of electromagnetism.
102. OPTIC NERVE The optic nerve is the second of twelve paired cranial nerves but is considered to be part of the central nervous system as it is derived from an out pouching of the diencephalons during embryonic development.
103. REFLECTION PRINCIPLE In set theory, a branch of mathematics, a reflection principle says that it is possible to find sets that resemble the class of all sets. There are several different forms of the reflection principle depending on exactly what is meant by "resemble".
104. REFLECTION FORMULA In mathematics, a reflection formula or reflection relation for a function f is a relationship between f(a-x) and f(x). It is a special case of a functional equation, and it is very common in the literature to refer to use the term "functional equation" when "reflection formula" is meant. Reflection formulas are useful for numerical computation of special functions. In effect, an approximation that has greater accuracy or only converges on one side of a reflection point (typically in the positive half of the complex plane) can be employed for all arguments. The even and odd functions satisfy simple reflection relations around a=0. For all even functions,
