(B) Let the angle between the two mirrors be $	heta.$ According to the problem,the incident ray is parallel to the mirror $(M_2).$ Therefore,the angle of incidence on the first mirror $(M_1)$ is $	heta.$ By the law of reflection,the angle of reflection from $(M_1)$ is also $	heta.$ This reflected ray strikes the second mirror $(M_2).$ In the triangle formed by the two mirrors and the light ray,the angle at the second mirror is $	heta$ (since the reflected ray is parallel to the first mirror $(M_1)$). Thus,the sum of angles in the triangle is $	heta + 	heta + 	heta = 180^o.$ $3	heta = 180^o$ $	heta = 60^o.$

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