A ray of light incident on the first mirror parallel to the second and is reflected from the second mirror parallel to first mirror. The angle between two mirrors is

Q. A ray of light incident on the first mirror parallel to the second and is reflected from the second mirror parallel to first mirror. The angle between two mirrors is

Q. Two plane mirrors are inclined to each other such that a ray of light incident on the first mirror $\left(M_1\right)$ and parallel to the second mirror $\left(M_2\right)$ is finally reflected from the second mirror $\left(M_2\right)$ parallel to the first mirror $\left(M_1\right)$. The angle between the two mirrors will be :

Q. Two plane mirror are inclined to each other such that a ray of light incident on the first mirror $\left(M_1\right)$ and parallel to the second mirror $\left(M_2\right)$ is finally reflected form th second mirror $\left(M_2\right)$ parallel to the first mirror $\left(M_1\right)$ the angle between the two mirrors will be :

Q. Two plane mirrors are inclined to each other at an angle ${60}^{\circ }.$ If a ray of light incident on the first mirror is parallel to the second mirror, it is reflected from the second mirror

Q. There are two plane mirrors placed at some angle $\theta$ with each other. A ray incident on first mirror (travelling parallel to second mirror) , travels parallel to the first mirror after two successive reflections. Find the angle $\theta$ between the mirrors.
