You get to find out how waves can be reflected or refracted. Perform experiments on refraction in order to demonstrate Snells law.
After completing this tutorial, you will be able to complete the following:
What happens when a wave encounters an obstacle?
~ When a wave encounters an obstacle, some of the energy carried by the wave is absorbed into the obstacle, while the rest reflects off the surface and moves in another direction.
How is the direction of reflected light rays from a surface related to the direction of incident light rays?
~ The angle of incidence of incident light rays is equal to the angle of reflection of reflected light rays.
What are the rules for a reflection?
~ The angle of incidence of incident light rays is equal to the angle of reflection.
