Two parallel, vertical, plane mirrors, 31.9 cm apart, face each other. A light source at point P is 29.8 cm from the mirror on the left and 2.1 cm from the mirror on the right.
(a) How many images of point P are formed by the mirrors?
(b) Find the distance from the mirror on the right to the two nearest images behind the mirror.
first nearest image=
second nearest image=
(c) Find the number of reflections of light rays for each of these images.
