Problem
A marine biologist notices that fish appear much closer when viewed through her diving mask underwater compared to when she observes them through the glass bottom of her research boat from above the surface. She measures that a fish appears to be 1.2m away when viewed through her mask underwater. The mask has a flat glass window with negligible thickness, and the fish is actually located horizontally at the same distance from the mask as it appears to be. However, when she views the same fish from directly above through the boat's glass bottom (also negligible thickness), the fish appears to be at a different depth. Given that the refractive index of water is n=1.33 and the refractive index of air is n=1.00, find the actual depth of the fish below the water surface.
