Question

28. How many images will be formed when
two plane mirrors are kept with reflecting faces
parallel to each other and the object is placed in
between them?
(a) Two
(b) Infinite
(c) One
(d) Four​

Answer 1

Answer:

option (b) infinite

Hence infinite number of images will be formed, Thus we obtain three images when an object is placed two mutually perpendicular mirrors. When two mirrors are placed parallel to each other, infinite images are formed.

Answer 2

Answer:

(b) Infinite

Explanation:

Number of images depends upon the number of possible reflections given by the formula 360/a where a is the angle between the two mirrors, here the angle approaches 0 hence the number of images formed approaches infinity
