Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What happens to light when it exceeds the critical angle while moving from a denser to a less dense medium?
- It refracts
- It is absorbed
- It reflects completely
💡 Hint: Consider what happens when light can’t pass through.
Question 2
True or False: The critical angle depends on the refractive indices of the two media.
- True
- False
💡 Hint: Reflect on how these indices are related.

Challenge Problems
Push your limits with challenges.
Question 1
A fiber optic cable is made of glass with a refractive index of 1.5 and is surrounded by air. Calculate the critical angle and explain how fiber optics use total internal reflection.
💡 Hint: Use the formula you've learned!
Question 2
Design an experiment to demonstrate total internal reflection using everyday materials. What results do you expect?
💡 Hint: Think about how you can change angles and observe the outcomes.
