This document discusses image formation using a converging lens. It defines key terms like principal axis and focal length. It presents three rules for drawing ray diagrams to determine the image location: rays parallel to the principal axis converge at the focal point on the opposite side, rays through the optical center pass straight through, and rays through the focal point are refracted parallel to the principal axis. The document explains that real images form when the object is over one focal length away, while virtual images form when the object is under one focal length away, as the refracted rays diverge in that case. No image is formed when the object is exactly at the focal length.

This document covers several key physics concepts related to light, including:
1) The law of reflection which states that the angle of incidence equals the angle of reflection.
2) The definition of real and virtual images, with virtual images unable to be projected onto a screen.
3) The rules of refraction regarding how light bends when slowing down or speeding up between mediums.
4) Total internal reflection, which occurs when light travels from an optically dense to less dense medium at an angle greater than the critical angle, causing all light to reflect inside the denser medium.
optics mirrors_and_lenses (1)
Mirrors and lenses reflect and refract light to form real or virtual images. Reflection off flat surfaces follows the law that the angle of incidence equals the angle of reflection. Concave mirrors can form real or virtual images depending on the position of the object. Convex lenses diverge light rays to form reduced virtual images, while concave lenses converge light to form real images that can be magnified or reduced. The eye focuses light using a convex lens, and conditions like nearsightedness and farsightedness occur when the eye is too long or short.
Optics mirrors & lenses
Optics is the study of light and its interactions with objects like mirrors, lenses, and substances that reflect, scatter, or transmit light. When light strikes an object, it can be reflected, transmitted, scattered, or absorbed. There are three main types of mirrors - plane, concave, and convex - and reflection follows the rule that the angle of incidence equals the angle of reflection. Refraction occurs when light changes speed as it passes from one medium to another, causing it to bend. Lenses use refraction to form real or virtual images depending on the position of objects in relation to the focal point.
Mirrors and lenses
This document discusses the uses and properties of lenses. It defines reflection and refraction, and describes how curved mirrors and different types of lenses work by bending light. Convex lenses converge light to a focal point, while concave lenses diverge light. Lenses are used in cameras, telescopes, and eyeglasses to focus light and form images. Cameras use lenses to admit more light and produce brighter, clearer pictures than a pinhole camera. The eye uses curved lenses to focus light onto the retina, and nearsightedness and farsightedness occur when the lens is too long or short. Telescopes also employ lenses and curved mirrors to magnify distant objects.

Optic, lens and iol
Light enters the eye and is refracted by the cornea and lens to be focused on the retina. The lens changes shape (accommodates) to focus on near and far objects. Over time the lens loses elasticity causing presbyopia where it can no longer accommodate. An intraocular lens (IOL) can be implanted during cataract surgery to replace the clouded natural lens and provide focus. IOLs vary in material, optic profile, power, and other factors to best suit the patient's needs.

Lenses can be either convex or concave depending on their thickness. A convex lens is thicker in the center and converges light rays, forming a real or virtual image. A concave lens is thinner in the center and diverges light rays, always forming a virtual image. The location and properties of an image formed by a lens depends on the position of the object relative to the lens's focal points, which can be determined using lens formulas and ray diagrams. Lenses are used in optical systems to focus and manipulate light in applications like cameras, microscopes, and eyeglasses.

Additionally, any ray passing through the center of either lens will continue in the same direction.

LENSES POWER POINT
Lenses are used in many optical devices like microscopes, telescopes, cameras, and projectors to refract light in a way that magnifies or projects images. There are two main types of lenses - convex lenses that converge light and concave lenses that diverge light. Lenses work by refracting light as they are made of curved surfaces of glass or other transparent materials that act like segments of a sphere or combination of prisms to bend light rays.
ray optics
1. Light rays travel in straight lines until interacting with matter. Rays reflect off mirrors and spherical lenses according to the law of reflection, where the angle of incidence equals the angle of reflection.
2. Plane mirrors form virtual upright images that are the same size as the object and as far behind the mirror as the object is in front. Spherical mirrors can form real or virtual images, depending on the position of the object relative to the focal point.
3. Concave mirrors form real enlarged images of objects placed between the center of curvature and focal point, and real reduced images of objects beyond the center of curvature. Convex mirrors always produce virtual upright reduced images.
Reflection of light
The document discusses key concepts related to reflection of light, including:
1) Luminous objects generate their own light, while illuminated objects reflect light. Reflection occurs when light bounces off a smooth, shiny surface at the same angle as it hits the surface.
2) The incident ray strikes the mirror, and the reflected ray leaves the mirror and strikes the eye, forming the line of sight from the image to the eye.
3) The angle of incidence equals the angle of reflection.
Reflection and Mirrors
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.
Ray optics and optical
This document summarizes key concepts in ray optics and optical instruments. It discusses phenomena of light including reflection, refraction, diffraction, scattering, polarization and interference. It also covers principles of spherical mirrors and aberration, refraction of light including Snell's law and refractive index, total internal reflection and its applications.

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.
Refraction of light in lenses
A lens is a transparent piece of glass with curved refracting surfaces that can be either convex or concave. Convex lenses are thicker in the middle and focus parallel rays of light to a focal point by converging the rays. Concave lenses are thinner in the middle and cause parallel rays of light to diverge as if originating from a focal point behind the lens. Lenses are used to either focus or diverge light depending on whether they are convex or concave.
P7 waves
The document discusses various properties of waves including:
1. Progressive waves carry energy from one place to another without transferring matter. Transverse waves have particle disturbance perpendicular to the direction of travel, like water waves.
2. A wavefront is a line where the disturbance is in the same phase, like wave crests. Reflection and refraction occur when waves pass from one medium to another, changing speed and direction.
3. Diffraction is the spreading of waves at obstacles. Wave theory can explain reflection, refraction, and the difference between transverse and longitudinal waves where particles vibrate along or perpendicular to the direction of travel.

Optics lenses--image-formation-worksheet
The document describes the properties of images formed by convex and concave lenses. It explains that a real image is formed when light rays converge on the opposite side of the lens, appearing inverted. A virtual image is formed when light rays diverge on the same side of the lens, appearing upright. The document then analyzes six cases of an object at different distances from a convex lens and concave lens to determine the corresponding image properties.
Lenses
This document discusses lenses and their effects on light. It explains that a converging lens brings parallel beams of light to a focal point, forming a real image. A diverging lens causes parallel beams to diverge, with a virtual focal point behind the lens. Real and virtual images are formed by converging lenses using ray diagrams and optical rules. Applications like cameras and magnifying glasses are also covered.

The document discusses the similarities between the human eye and a camera. Both have an aperture that controls the amount of light (pupil in the eye, diaphragm in the camera). The document also discusses common vision defects like myopia and hyperopia and how lenses are used to correct them. It then explains how images are formed by reflection in plane mirrors and curved mirrors, and by refraction through lenses. Ray diagrams are used to determine the nature and location of images formed by mirrors and lenses.
Lenses in Optics
The document discusses the principles of image formation using lenses and how lenses are used in corrective lenses. It covers the basics of refraction, how converging and diverging lenses form images using ray tracing rules, and examples of how converging and diverging lenses can correct for nearsightedness and farsightedness by forming intermediate images at the appropriate focal points for the eye. Diagrams illustrate the ray tracing and image formation for different types of lenses. Exercises provide examples of using the ray tracing rules to locate images.
Lenses
Lenses are transparent materials that refract light in a predictable way. They are used to magnify or project images. There are two main types of lenses: convex and concave. Convex lenses are thicker in the center and converge light, forming a real image. Concave lenses are thinner in the center and diverge light, forming a virtual upright image that is smaller than the object. The way light rays behave when passing through lenses can be depicted using ray diagrams to show the characteristics of the image formed.
Convex Lens - A Complete Overview.PDF
A lens is a transparent material that concentrates or disperses light rays when it passes through them by refraction. According to the shape and purpose of the lens, they are classified into two types convex lens and concave lens. Let’s learn about convex lenses in detail in this article.
U10 Cn2 Lens Intro
This document provides an introduction to converging and diverging lenses. It discusses how converging lenses bring parallel rays of light together at a focus, while diverging lenses spread them apart as if from a focus. Convex lenses are generally converging, while concave lenses are generally diverging. Lenses can form real or virtual images. Real images can be projected on a screen, while virtual images cannot. The document also outlines the ray tracing rules for determining the path of light through converging and diverging lenses.
LENSES.pptx
Lenses work by refracting light rays using the principle of refraction. There are two main types of lenses: convex and concave. A convex lens is thicker in the middle and converges light rays, forming a real, inverted, and reduced image. A concave lens is thicker on the edges and diverges light rays, forming a virtual, upright, and reduced image. Ray diagrams can be used to determine the location, orientation, size, and type of image formed by a lens by tracing the path of three key rays: the parallel, focal, and vertex rays.

An image is a reproduction of an object via light that can either be real, forming on a surface, or virtual, requiring an observer. Real images are produced by concave mirrors and converging lenses, whereas virtual images are produced by flat mirrors. A real image occurs where rays converge and a virtual image where rays appear to converge. Concave mirrors form real images when the object is outside the focal point and virtual images when inside the focal point. Lenses also form real or virtual images depending on if the object is outside or inside the focal point. Diffraction occurs when light encounters an obstacle comparable in size to its wavelength, spreading the waves and creating interference patterns like Newton's rings.
Light - Mirrors and Lenses.pptx
Plane mirrors form virtual images that are laterally inverted and the same distance behind the mirror as the object is in front of it. Curved mirrors can be either concave or convex. Concave mirrors produce real or virtual images depending on the position of the object, while convex mirrors only produce virtual images. Lenses can be either converging or diverging. Converging lenses are thicker in the middle and can form real or virtual images, while diverging lenses are thicker on the edges and always form virtual images.

P8 converging lens
- 1. Image formation by a converging lens
- 2. Know the terms: Principal axis / optical centre / principal focus / focal length
- 5. 3 Rules to follow: 1.draw the ray parallel to the principal axis and it converges through the principal focus (F) on the other side 2. draw the ray through the optical centre and it passes through in a straight line (not refracted) 3. draw the ray through the principal focus on the object side of the lens and it is refracted parallel to the principal axis!
- 6. Where is the image?
- 7. Do you need convincing?
- 8. Why does the ray from the bottom of the object appear on the principal axis? What can we say about the image: • Inverted or Upright position? • Reduced or Magnified? •Its location(related to 2F and which side it appears on)
- 9. Where is the object? Where is the image?
- 10. Can an image be bigger than the object?
- 11. Magnifying glass
- 12. Real or Virtual? Real images are produced when the object is located a distance greater than one focal length from the lens. A virtual image is formed if the object is located less than one focal length from the converging lens. When refracted rays diverge, a virtual image is formed because the rays cannot be focused onto a screen.
- 13. Explaining the virtual image. When refracted rays diverge, a virtual image is formed. The image location can be found by tracing all light rays backwards until they intersect. The refracted rays seem to be diverging from this point; thus, the point of intersection of the extended refracted rays is the image point. Since light does not actually pass through this point, the image is referred to as a virtual image.
- 14. Wierd / Strange / X files?
- 15. Object at F gives no image! The light rays neither converge nor diverge after refracting through the lens. The refracted rays are traveling parallel to each other. So, the light rays will not converge to form a real image; nor can they be extended backwards on the opposite side of the lens to intersect to form a virtual image.
- 16. Remember: 3 Rules to follow! 1.draw the ray parallel to the principal axis and it converges through the principal focus (F) on the other side 2. draw the ray through the optical centre and it passes through in a straight line (not refracted) 3. draw the ray through the principal focus on the object side of the lens and it is refracted parallel to the principal axis!
- 17. Object location: Image location: Image size: Image position:
- 19. Object location: Image location: Image size: Image position:
- 21. Object location: Image location: Image size: Image position:
- 23. Object location: Image location: Image size: Image position:
- 25. Well done!
