Two vertical plane mirrors are inclined at an angle of 600 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 plane mirrors are inclined to each other at an angle of 700. A ray is incident on one mirror at an angle θ. The ray reflected from this mirror falls on the second mirror from where it is reflected parallel to the first mirror. Determine the value of θ.
Two plane mirrors are inclined to each other at an angle 60∘. If a ray of light incident on the first mirror is parallel to the second mirror, it is reflected from the second mirror
Two plane mirrors are inclined to each other at an angle θ. A ray of light is reflected first at one mirror and then at the other. The total deviation of the ray is
Two plane mirrors are inclined at an angle of 60o with each other. An incident ray hits one of the mirror at an angle of 80o with the normal. Its angle of deviation after two reflections is
