Question

Infinite number of images are formed when two plane mirrors face each other.

• A. True
• B. False

Answer 1

The correct option is A True

1. When two plane mirrors are kept parallel to each other, an infinite number of images are formed.
2. We can assure this with the formula for multiple reflections.

I.e., N = 360θ−1

3. For parallel mirrors, θ = 0.

4. Therefore, N = (3600)−1 which is taken as infinite.

Hence the above statement is true.
