Free-response Problems Each answer in the following problems is worth 4 points. 11. A glass beaker contains a transparent colorless liquid (of unknown refractive index). A light ray is incident on the liquid at an angle of 30.0°, as shown. The light ray travels through the liquid, and hits the side of the beaker at the critical angle. (The refractive index of the glass is 1.60).
Find:
(a) The refractive index of the unknown liquid
(b) The angle 02. 30.00
