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.
