A beam of light enters a block of flint glass (n=1.65) at 24 degree angle from the normal. Calculate the path the light takes until it leaves the glass. Calculate the exact angles the light travels at each time it refracts or reflects, remember that the normal for the side of the glass block is perpendicular to the normal for the top of the glass block. Assume all of the coners of the glass block are right angles.
