Question:

Two plane mirrors arc inclined to each other such that a ray of light incident on 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 :

$90^{\circ}$
$45^{\circ}$
$75^{\circ}$
$60^{\circ}$

Hide Solution

Verified By Collegedunia

The Correct Option is D

Solution and Explanation

Assuming angles between two mirrors be $\theta$ as per geometry, sum of anlges of $\Delta$ $3 \theta = 180^{\circ}$ $\theta = 60^{\circ}$

Reflection of Light

When a light ray falls on any object, it is bounced back from the object. This process is known as the Reflection of light. The light reflected from the object falls into our eyes, making the object visible to us. All the things we see around us are because of reflection.

The reflection of light depends on the type of object. A polished or smooth surface reflects most of the light falling on it, while a rough surface absorbs some amount of light and reflects back the rest of the light. The direction of reflected rays depends upon the surface of the object.
