Find the number of images formed when a candle is placed between two mirrors inclined at an angle of ${60}^0$.

1. 5

The correct option is A 5
Two plane mirrors are kept inclined to each other at an angle, $={60}^0$
$n=\frac{360}{\theta }=\frac{360}{60}=6$
As n is an even number,
Number of images $=n-1=5$

Therefore, $5$ images will be formed
