Question

Two mirrors are placed at right angles to each other as shown in the figure. Total number of images of an object O placed between them, that are seen are:

• A. Two
• B. Three
• C. Four
• D. Six

Answer 1

The correct option is B Three

$\theta ={90}^o$
$n=\frac{360}{\theta }=\frac{360}{90}=4\left(even\right)$
Number of images $=n-1$
$=4-1=3$
