- 1. When one light ray is reflected from a plane mirror with \(30^{\circ}\) angle of reflection, the angle of deviation of the ray after reflection is \(.....^{\circ}\) 2023 Easy
- 2. A light ray is incident, at an incident angle \(\theta_{1}\), on the system of two plane mirrors \(M_{1}\) and \(M_{2}\) having an inclination angle \(75^{\circ}\) between them (as shown in figure). After reflecting from mirror \(M_{1}\) it gets reflected back by the mirror \(M _{2}\) with an angle of reflection \(30^{\circ}\). The total deviation of the ray will be \(\dots\) degree.
