A light ray is incident, at an angle θ1, on a system of two plane mirrors M1 and M2 having an inclination angle of 75° between them. After reflecting from mirror M1, it gets reflected back by mirror M2 with an angle of reflection of 30°. The total deviation of the ray will be _______ degrees.

What are the characteristics of an image formed by a plane mirror?

Given below are two statements: an Assertion [As] and a Reason [R]. Assertion [As]: A convex mirror cannot form real images of real objects. Reason [R]: Convex mirrors converge the parallel rays of light that are incident on them. Choose the correct alternative:
