Problem
An underwater photographer is taking pictures of fish through the glass window of an aquarium. The aquarium glass has thickness t=2.5cm and refractive index ng=1.52. Water has refractive index nw=1.33, and air has na=1.00. A fish is located at distance d=15.0cm from the inner surface of the glass wall.
Due to refraction at the two glass surfaces, the fish appears to be at a different location than where it actually is. Calculate the apparent distance of the fish from the outer surface of the glass wall, as seen by the photographer in air.
