My Notes Ask Your Teacher A layer of water, with index of refraction 1.333, rests on a block of an unknown transparent material. A ray of light passes through the water at an angle of 1 = 66.770 relative to the boundary between the materials and then passes through the unknown material at an angle of P2 = 72.18° relative to the boundary What is the speed of light in the unknown material? 2e+08 m/s tO Ask me anything 9:43 AM 4/25/2016

Solution

theta_c = sin^-1[1/1.42] = 44.75°

theta₀= theta_c - 13° = 31.75°

theta_i = sin^-1[sin theta₀ * 1.42]

= sin^-1[sin 31.75* 1.42]

= 48.33°
