1. Consider light, which is initially traveling in air, being reflected from a diamond (n = 2.35).

Part (a) At what angle, with respect to the normal of the surface, will the light reflected from the diamond be completely polarized?

2. A student notices that the image produced from a large concave mirror of a distant skyscraper (h = 138 m) is inverted and the magnitude of the height is |hi| = 0.75 m tall. The image is located d = 156 cm in front of the mirror.

Part (a) Write an expression for the distance between the mirror and the skyscraper, ds.

Part (b) Numerically, what is the distance in meters?

Part (c) Numerically, what is the focal point of the mirror, f, in cm?

3. Consider a makeup mirror that produces a magnification of 1.7 when a person's face is 12.5 cm away.

Part (a) What is the focal length of the makeup mirror in m?
