# Refraction of light: Apparent depth of a pool

A coin is lying at the bottom of a pool of water that is 4.90 ft deep. Viewed from directly above the coin, how far below the surface of the water does the coin appear to be? (The coin is assumed to be small in diameter. Therefore, we can use the small angle approximations sinθ = tanθ = θ.)

Please solve and explain
