2. The following figure shows a ray of light in a material of unknown refractive index of air (n = 1.00029). When the incident angle is 27.0 degrees and the angle of refraction is 18.0 degrees, which is the refractive index of the material, the second? http://i33.photobucket.com/albums/d77/alexsierra82/QUIZ1037PIC2.jpg

3. The following figure shows a ray of light from one material to another, then another. Given the relative angle of the light rays in the figure, which of the following best describes the relative size indices of refraction?
