Two plane mirrors are inclined to each other such that a ray of light incident on the first mirror $\displaystyle \left(\mathrm{M}_1\right)$ and parallel to the second mirror $\displaystyle \left(\mathrm{M}_2\right)$ is finally reflected from the second mirror $\displaystyle \left(\mathrm{M}_2\right)$ parallel to the first mirror $\displaystyle \left(\mathrm{M}_1\right)$. The angle between the two mirrors will be :
Official answer
(2)
$\displaystyle 60$°
