Question

I am having a lot of trouble with this physics question. I ahve tried working this a few times already, and I have been wrong every time. Here is the question:

A prism made of flint glass has a cross section that is an equilateral triangle. The index of refraction for red and violet light respectively in flint glass is 1.662 and 1.698. If as shown in the figure, the angle of incidence in air for both colors of light is 63.3degree determine the angle at which both colors emerge back into air after traveling through the prism. red light Have you drawn a careful figure to show how the path for violet light will differ from the path or red light? Have you looked for relations among the various angles in your diagram? violet light Can you write Snell's law for both red and violet light as they travel from air and into the flint glass prism and then again as they emerge from the prism and refract in air?

Explanation / Answer

using snails law

n1 sin r1 = n2 sin r2

so for red color

sin r2 = sin r1/ 1.662 = 0.537 so sin r2 = 32.51 degree

similarly for violet sin r2 = sin r1/ 1.698 = 31.744 degree
