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