Chapter 32, Problem 66GP
Two identical concave mirrors are set facing each other 1.0 m apart. A small lighlbulb is placed halfway between the mirrors. A small piece of paper placed just to the left of the bulb prevents light from the bulb from directly shining on the left mirror, but light reflected from the right mirror still reaches the left mirror. A good image of the bulb appears on the left side of the piece of paper. What is the focal length of the mirrors?

You can see part of the back of your head if you have two mirrors mounted at an acute angle. The picture shows a top view of this with a ray of light that starts at the side of your head, reflects off both mirrors and to your eye. If you are standing equidistant from both mirrors and the angle between the mirrors is 67.4o, what is the angle of reflection from the first mirror? Please give your answer in degrees.

- Use a ruler and a protractor to draw rays to find images in the following cases. (a) A point object located on the axis of a concave minor located at a point within the focal length from the vertex. (b) A point object located on the axis of a concave mirror located at a point farther than the focal length from the vertex. (c) A point object located on the axis of a convex mirror located at a point within the focal length from the vertex. (d) A point object located on the axis of a convex mirror located at a point farther than the focal length from the vertex. (e) Repeat (a)—(d) for a point object off the axis.arrow_forwardSuppose a man stands in front of a mirror as shown in Figure 25.50. His eyes are 1.65 m above the floor, and the top of his head is 0.13 m higher. Find the height above the floor of the top and bottom of the smallest mirror in which he can see both the top of his head and his feet. How is this distance related to the man’s height?
