At a department store, you adjust the mirrors in the dressing room so that they are parallel and 8.0 ft apart. You stand 3.6 ft from one mirror and face it. You see an infinite number of reflections of your front and back. (a) How far from you is the first "front" image? ft (b) How far from you is the first "back" image?

A concave mirror (f1 = 6.00 cm) and a convex mirror (f2 = −9.00 cm) are facing each other and are  separated by a distance of 30.0 cm. An object is placed halfway between the mirrors. Consider the light from the object to reflect first from the concave mirror and then from the convex mirror.   a) What is the distance of the first image (di1) that is produced by the concave mirror? b) What is the magnification (m1)?  c) Find the distance of the object for the convex mirror (do2)?  d) What is the distance of the final image (di2) produced by the combination of the two mirrors? e) What is the magnification (m2)?  f) What is the overall magnification (m)?  g) Describe the final image formed by the combination of the two mirrors.

Two plane mirrors make an angle α = 54.0◦ between them. A ray of light incident on one of the mirrors is reflected and hits the second mirror. Find the angle β between the ray incident on the first mirror and the ray reflected off of the second mirror. (a) 36.0◦ (b) 72.0◦ (c) 54.0◦ (d) 24.0◦ (e) None of the above.

The spherical side mirror on a car is convex and has a radius of curvature of 23 cm. Another car is following, 2.2 m behind the mirror. If the height of the car is 1.15 m, how tall is its image?
