Challenge Problems
Push your limits with challenges.
Question 1
A person looks at a quarter submerged in a glass of water at an angle. If the quarter appears to be 45% larger than its actual size, calculate the angle of refraction using the formula for refractive index.
💡 Hint: Consider how the refractive index will influence the perceived size and angle.
Question 2
Assuming light travels in a medium with a refractive index of 1.5, if the incident ray is at 30 degrees, what is the angle of refraction?
💡 Hint: You'll need to calculate the sine of both angles.
