Reference no: EM13271405

A flint glass plate (n = 1.66) rests on the bottom of an aquarium tank. The plate is 8.50 cm thick (vertical dimension) and covered with water (n = 1.33) to a depth of 11.9 cm. Calculate the apparent thickness of the plate as viewed from above the water. (Assume nearly normal incidence of light rays.)
