A thick sheet of plastic, n = 1.500, is used..?

A thick sheet of plastic, n = 1.500, is used as the side of an aquarium tank. Light reflected from a fish in the water has an angle of incidence of 35 degrees. At what angle does the light enter the air??A thick sheet of plastic, n = 1.500, is used..?
okay use Smelt's Law:





(n1) * (Sin @1) = (n2) * (Sin @2)


1.5 * Sin 35 = 1 * Sin x


0.86 = Sin x


x = 59.36掳





hope this helps^_^
