Refraction of Light Demonstration
http://www.control.co.kr/java1/RefractionofLight/LightRefract.html
In this interactive demonstration, you have control over the following
variables;
incident angle, medium (material), and incident wavelength.
By experimenting, answer the following questions.
1. At what angle does no refraction occur? __________________
2. What does it mean if there is a very large difference between the incident angle and the reflected angle?

4. What medium (in this demonstration) refracts light the least? ____________________________
5. Describe, using complete sentences, what happens when light passes from air into another medium.
