A ray of light incident on the first mirror and parallel to the second mirror in reflected from the second mirror parallel to the first mirror .The angle between the two mirrors is

Two plane mirrors are inclined to each other such that a ray of light incident on the first mirror and parallel to the second is reflected from the second mirror parallel to the first mirror. Determine the angle between the two mirrors:

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 plane mirrors are inclined at 70^@ . A ray incident on one mirror at incidence angle theta after reflection falls on the second mirror and is reflected from there parallel to the first mirror, The value of theta is

A light ray incident on a plane mirror gets reflected from it. Another plane mirror is placed such that the reflected ray from the first mirror is incident on it If the reflected ray from the second mirror travels perpendicular to the indecent ray on the first mirror, determine the angle between two plane mirrors.
