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

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 ?

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 placed perpendicular to each other. A ray strikes one mirror and after reflection falls on the second mirror. The ray after reflection from the second mirror will be

Two plane mirrors are inclined at angle theta .A ray of light is incident on one mirror at an angle of incidence.i.The rayis refelected from this mirror,falls on the second mirror from where it is refleced parallel to the first mirror .What is the value of i,the angle of incident in term of theta ?
