Vedclass · Answer

(B) Let the mirror $M$ be inclined at an angle $	heta$ with the horizontal $H$. The incident ray makes an angle $	heta$ with the mirror surface. According to the law of reflection,the angle of reflection is equal to the angle of incidence. Therefore,the reflected ray also makes an angle $	heta$ with the mirror surface. From the geometry of the setup,the angle between the reflected ray and the horizontal is the sum of the angle the reflected ray makes with the mirror and the angle the mirror makes with the horizontal. Thus,the angle with the horizontal is $	heta + 	heta = 2	heta$.

$A$ mirror is inclined at an angle of $\theta$ with the horizontal. If a ray of light is incident at an angle $\theta$ with the mirror,then the reflected ray makes the following angle with the horizontal:
