[5] (similar to chapter 24, problem 16)
A hiker is lost somewhere near Mt. Whitney, which she
knows has an elevation of 4600 m. To determine her dis tance from the mountain, she uses her compact mirror, a
small concave mirror with a focal length of 20 cm. She
views an image of the mountain in her mirror, and notes
that when the mirror is held about 50 cm from her eyes,
the image covers a section of the mirror about 5 cm
high. How far is Mt. Whitney?

Question
[9-10] (similar to chapter 24, problem 29ab)
A laser beam 1.0 mm in diameter is directed along
the optical axis of a thin lens of focal length 5.0 cm
(Fig. 24–58).
[9] How far from the lens will the beam be focused?
[10] A second positive lens is placed to the right of the
first. Light emerges from the second lens in a par allel beam of diameter 4.0 mm. Thus the combination
of lenses acts as a beam expander. Find the focal
length of the second lens and the distance between
the lenses.
