Optics is the study of visible light and how it interacts with the eye to produce vision. The document discusses key optics concepts such as the law of reflection, which states that the angle of reflection equals the angle of incidence, and different types of reflection from smooth and rough surfaces. It also covers how the shape of mirrors determines the type of image formed, such as flat mirrors showing an exact image, convex mirrors producing a smaller image, and concave mirrors creating upside-down or right-side-up images depending on the distance from the focal point where light rays meet.

2. What is optics?
 Optics is the study of visible light and the ways in
which visible light interacts with the eye to produce
vision.

3. Law of Reflection
 Law of Reflection- states that the angle of reflection
equals the angle of incidence

4. Regular Reflection
 Regular Reflection- the reflection of parallel light rays
all in the same direction
 Occurs on smooth surfaces

5. Diffuse Reflection
 Diffuse Reflection- the reflection of parallel light rays
in many different directions
 Occurs on surfaces that are not smooth
 Some may feel smooth to the touch (like paper), but are
actually full of texture

6. Shape determines how mirrors
form images
 An image is a picture of an object formed by light.
 Flat mirrors show an image that looks exactly like
you.
 Convex mirrors (curved outward) the image will
appear smaller than you.
 Concave mirror (curved inward)
 Far way- image upside down and smaller
 Close up- right-side up and bigger

7. Focal Point
 Focal point- the point at which the rays meet
