Challenge Problems
Push your limits with challenges.
Question 1
A beam of light enters a new medium at 45Β° and bends to 30Β°. Find the refractive index. Discuss what this value implies about the medium.
π‘ Hint: Use the sine relationship and analyze the implications of density.
Question 2
Consider light transitioning from glass to water. Given the refraction angles, analyze how the refractive indices could differ and impact sight.
π‘ Hint: Think about how each medium affects light perception and bending.
