2. Learning goals We are learning the types of reflection.
We are learning the laws of reflection.
We are learning to draw images in plane mirrors.

3. terminology Ray Diagrams: show rays of light that an observer sees.
Only a few representative rays are drawn
Light Ray: line representing the direction and path that light is travelling

4. Reflection: light bouncing off a non-luminous object
Regular/Specular: light reflects off a smooth surface
Image is clear
Ex. Smooth water

5. Diffuse Reflection: light reflects off a rough surface
Difficult to predict where the light will reflect
Image is blurred
Ex. Rough water

13. Laws of reflection
1. The angle of incidence equals the angle of reflection.

14. Laws of reflection
2. The incident ray, the reflected ray, and the normal all lie in the same plane.
