Unformatted text preview: Homework 2 Chapt. 23 23.15. Model: Represent the laser beam with a single ray and use the ray model of light. Solve: Using Snells law at the air-water boundary, air air liquid liquid sin sin n n = air liquid air liquid sin sin37 1.0 1.37 sin sin 26 n n = = = Assess: As expected, n liquid is larger than n air . 23.22. Model: Use the ray model of light. Visualize: Solve: Using Snells law, air red red sin30 sin n n = 1 red sin 30 sin 19.2 1.52 - = = air violet violet sin30 sin n n = 1 violet sin30 sin 18.8 1.55 - = = Thus the angular spread is red violet 19.2 18.8 0.4 =- = - = 23.58. Model: Use the ray model of light. Solve: (a) Using Snells law at the air-glass boundary, with being the angle of refraction inside the prism, air sin sin n n = sin sin n = Considering the triangle made by the apex angle and the refracted ray, ( ) ( ) 1 2 90 90 180 - + - + = = Thus ( ) ( ) 1 1 1 2 2 sin sin sin...
