Mission RL4: Snell's Law

Mission RL4 targets student's ability to use Snell's Law of refraction in a problem-solving context to deterimine an unknown value of the index of refraction or the angle of refraction. The mission consists of 30 questions organized into 8 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 use Snell's law to algebraically solve for an unknown quantity (such as the index of refraction or the angle of refraction).

• What is the angle of incidence and how is it measured?
• What is the angle of refraction and how is it measured?
• What happens when a light ray approaches a boundary head onat a 90 degree angle to the boundary?
• How can one use angle measurements to determine the index of refraction of a material?
• How can one use index of refraction values and an angle of incidence to predict the angle of refraction?
