Mission RL2: Light Speed and Refraction

Mission RL2 focuses on the terms angle of incidence and angle of refraction and on the relationship between the speed of light in two media and the direction light bends when passing from one medium to the other. The mission consists of 36 questions organized into 9 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...
 

Learning Outcomes

• The student should be able to identify the angle of incidence and the angle of refraction.
• The student should be able to relate the direction which light bends (towards or away from the normal) if given the relative speed of light in the two media.
