Problem 11

  Repeat problem 10 for a concave mirror with a focal length of 20.0 cm, an object distance of 12.0 cm, and a 2.0-cm-high object.

The relevant part of problem 10 is ``Using a ray diagram drawn to scale, measure (a) the location and (b) the height of the image. The mirror must be drawn to scale.''

SOLUTION: It's dorky to draw things with characters, so I won't even embarrass myself (this time). The answers are (a) the image is 30 cm behind the mirror, and (b) the image height is 5 cm, erect.
