Question: A ray of light is incident on the mid-point of a glass prism surface at an angle of 20º with the normal. For the glass, n = 1.60, and the prism apex angle is 35º.
A- What is the angle of incidence at the glass-to-air surface on the side opposite where the ray exits the prism?
Please use as much detail as possible in your answer. Thanks.
