Chapter , Problem 38(choose chapter or problem)
Figure 31-57 shows a beam of light incident on a glass plate of thickness and index of refraction (a) Find the angle of incidence so that the separation b between the ray reflected from the top surface and the ray reflected from the bottom surface and exiting the top surface is a maximum. (b) What is this angle of incidence if the index of refraction of the glass is 1.60? (c) What is the separation of the two beams if the thickness of the glass plate is 4.0 cm?
