How far from a concave mirror (radius 25.0 cm ) must an object be placed if its image is to be at infinity?
Express your answer to three significant figures and include the appropriate units.
A concave mirror has a focal length of 40.6 cm. The distance between an object and its image is 74.8 cm. Find (a) the object and (b) image distances, assuming that the object lies beyond the center of curvature and (c) the object and (d) image distances, assuming that the object lies between the focal point and the mirror.
Your height as you dress in front of a spherical mirror in the morning for your 7:30 class is h. The absolute value of the focal length of the spherical mirror is20.3 cm. If your image has the same upright orientation with its height h’=0.1779h, then calculate how far (in cm) you are standing from the mirror.
