Problem 14-37 Snell's Law - B

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
