Question 1
What does the refractive index (μ) represent?
- A measure of light's speed in a vacuum
- A measure of how much light bends in a medium
- The angle of incidence
💡 Hint: Think of how light behaves at different materials.
Question 2
Is total internal reflection possible when light moves from a denser to a rarer medium? True or False.
- True
- False
💡 Hint: Recall the conditions needed for total internal reflection.

Challenge Problems
Push your limits with challenges.
Question 1
A light ray strikes a glass interface at an angle of 30°. If the refractive index of glass is 1.5, what is the corresponding angle of refraction in the glass?
💡 Hint: Rearrange Snell's Law to solve for the unknown angle.
Question 2
If you have a prism made of material with a refractive index 1.67, and light hits it at the critical angle. How would this affect light traveling out of the prism?
💡 Hint: Consider the relationship of the critical angle and its effect on specific incidences.
