A beam of light falls perpendicularly on the surface of a triangular prism.

Draw the beams path through the prism. Show any necessary calculations.

n = 1.5

2. Relevant equations

n_{1}sin(a) = n_{2}sin(b)

maybe, not sure tbh.

3. The attempt at a solution

This is what I did to find the angles:

1.5 = sin 90°/sin(b)

1.5 sin(b) = sin 90°

sin (b) = sin 90° /1.5

sin (b) = sin^{-1}0.66

b = 41.8°

I have no idea whether I'm right or not, I asked my teacher how to do it but she did it in a hurry so I didnt understand what she was talking about.
