### Lesson Focus

#### Listing Reflection Laws

Physics

You get to find out how waves can be reflected or refracted. Perform experiments on refraction in order to demonstrate Snell’s law.

### Now You Know

After completing this tutorial, you will be able to complete the following:

• State the laws of reflection.
• State that the laws of reflection can be applied to both water and sound waves.

### Everything You'll Have Covered

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.

### Tutorial Details

 Approximate Time 2 Minutes Pre-requisite Concepts Students should be able to define the following terms: angle of incidence, angle of reflection, and laws of reflection. Course Physics Type of Tutorial Animation Key Vocabulary angle of incidence, angle of reflection, laws of reflection
