Question

Find the number of images formed by the system of plane mirrors arranged as shown in the figure. The object ${}^{\prime }{\text{O}}^{\prime }$ is placed at the midpoint of $\text{PQ}$.

• A. $2$
• B. $1$
• C. $3$
• D. $4$

Answer 1

The correct option is A $2$


From the ray diagram, it is clearly evident that $2$ images $I_1$ and $I_2$ are formed .

To form multiple images, multiple reflections must happen,

After reflection for the first time, the reflected rays never hit the other mirrors.
