Challenge Problems
Push your limits with advanced challenges
If you know the angle of incidence is 60° and the refractive index of glass is approximately 1.5, calculate the angle of refraction.
💡 Hint: Start with the sine function for both angles.
A ray of light passes from air (n=1) into water (n=1.33) at an angle of 30°. Calculate the angle of refraction.
💡 Hint: Use sine relationships carefully.
