Question

A night watchman enters the local aquarium where the lights are out, and he uses his high-power flashlight to look for the fish inside. The parallel beam of light illuminates a fish when the angle of the beam with respect to the horizontal base of the aquarium is ?1 = 46.0?. The flashlight is level with the bottom of the aquarium and 40.0 cm from its glass window, while the fish inside the aquarium is 50.0 cm from the other side of the glass. The glass is 10.0 cm thick and has a refractive index nglass = 1.52. The refractive index for the water is nwater = 1.33 and for the air nair = 1.00. What is the distance y between the fish and the bottom of the aquarium?

What is the distance y between the fish and the bottom of the aquarium?
