Two mirrors meet at an 125 degree angle. If light rays strike one mirror at 125 degrees, what angle do they leave the second mirror? I got 5 degrees and I tried negative 5 degrees, but both of those answers are wrong.

A diver shines a flashlight upward from beneath the water at a 47.5 degree angle to the vertical. At what angle does the light leaver the water. I got 71.5 degrees, and that answer was incorrect.

LIght is incident on an equlateral crown glass prism at a 42 degree angle to the normal on one face. Calculate the angle at which light emerges from the oppoiste face. Assume n = 1.56. I tried this problem twice, and got two wrong answers.

Can someone please help me :)
