State your answer with the correct sign. 2. A convex mirror has a radius of curvature of 36.0 cm. When a 5.60 cm tall object is placed in front of the mirror, the magnification is 0.250. (a) What is the height of the image? (b) How far is the object from the mirror? 3. A double-paned window consists of two parallel panes of glass with an air gap between them. The outside pane has an index of refraction of 1.61 while the inside layer has an index of refraction of 1.51. If light enters the window from outside at 21.0 ° to the normal, at what angle to the normal does it exit the window on the inside? 4. You are constructing a fiber optic cable. You wish to surround the core of the cable with a cladding material such that the critical angle to go from the core to the cladding is 73.0 ° . If the index of refraction of the core material is 1.61, what must the index of refraction of the
