# Problem 14-37 Snell's Law - Part 2 - C

A red laser beam enters a crown glass prism in the shape of an equilateral triangle. The angle of incidence is $60.0^\circ$ and the index of refraction for the red light in the prism is $1.51$. Determine the angle of refraction in the glass and the angle of emergence in the air. (Hint: A diagram will help, especially in finding the angle of emergence. [Ans. $35.06^\circ; 39.7^\circ$]

Accumulated Solution

Correct!

Snell's Law states:

(A)   $n_1 \sin \theta_1 = n_2 \sin \theta _2$

(B)   $n_2 \sin \theta_1 = n_1 \sin \theta _2$

(C)   $n_1 /\sin \theta _1 = n_2 /\sin \theta_2$
