Question

A comer reflector is placed on the bottom of a lake. Light is shined from a boat at an angle of 35° to the surface of the water, strikes the comer reflector, and passes through the water and back into the air. At what angle to the surface does the light leave the water? Note: It is a property of a comer reflector that it reflects light back along a path that is parallel to its original path. Round-off your final answer in two decimal places. No unit required.
