1. A light ray propagates in a transparent material at 15 to a surface normal. It emerges into the surrounding air at 24° to the surface normal. Determine the index of refraction of the material. 2. A light bulb is 4.00 m from a wall. You are to use a concave mirror to project an image of the lightbulb on the wall, with the image 2.25 times the size of the object. How far should the mirror be from the wall?
