Solution

The correct option is C
Three

We use the formua $n = (\frac{360^{\circ}}{Θ}) - 1$ . Which gives $(\frac{360^{\circ}}{90^{\circ}}) - 1$ = 3
Hence three images are formed.

Periscope works on the principle of multiple reflection. It consists of two or more mirror, used for the reflection. If the two mirrors are placed at an angle of 90∘, how many images of the object are formed between them?

The correct option is C Three We use the formua n=(360∘Θ)−1. Which gives (360∘90∘)−1 = 3 Hence three images are formed.
