there's a triangular prism with sides 8 cm, 10 cm, and 5 cm made out of material of n = 1.9 is submerged in an aquarium of water with n = 1.333. A ray of light strikes the 8 cm long side precisely in the middle and at 24 degrees relative to the normal. Work out all the angles that you need to work out and calculate the angle that the ray emerges at. (this might take the law of sines or the law of cosines to do.)
the explanation is perfectly understandable
