Two plane mirrors are inclined at an angle `theta` with each-other. A ray of light strikes one of them. Find its deviation after it has been reflected twice-one from each mirror.

Two plane mirrors are inclined at an angle theta to one another. A ray of light incident on the first mirror and parallel to the second mirror is reflected from the second mirror parallel to the first mirror. What is the value of theta ?

Two vertical plane mirrors are inclined at an angle of 60^(@) with each other. A ray of light travelling horizontally is reflected first from one mirror and then from the other. The resultant deviation is

Two vertical plane mirrors are inclined at an angle of 60^(@) with each other. A ray of light travelling horizontally is reflected first from one mirror and then from the other. The resultant deviation is

If two plane mirrors are inclined at angle 0 to each other as shown, than angle of deviation of incident ray is

Two plane mirrors are inclined to each other at an angle theta . A ray of light is reflected at one mirror and then at the other. Find the total deviation of the ray.

Two plane mirrors are inclined to each other at an angle theta . A ray of light is reflected at one mirror and then at the other. Find the total deviation of the ray.
