Two plane mirror `M_(1)` and `M_(2)` area inclined at angle `theta` as`
` shown. A ray of light 1, which is parallel to `M_(1)`strikes `M_(2)` and after two
reflection , the ray 2 become parrallel to `M_(2)`.Find the angle `theta`

Two plane mirrors M_(1) and M_(2) are inclined at angle as shown in Figure . A ray of light1, which is parallel to M_(1) , strike M_(2) and after two reflections, ray 2 becomes parallel to M_(2) . Find the angle theta .

Two plane mirrors are inclined at an angle of 60^@ as shown in Figure. A ray of light parallel to M_(1) strikes M_(2) . At what angle will the ray finally emerge?

Two plane mirror M_(1) "and" M_(2) are inclined to each other at 70^(@) . A ray incident on the mirror M_(1) at an angle theta fallls on M_(2) and is then reflected parallel to M_(1) for

Two plane mirrors are inclined at angle theta as shown in figure. If a ray parallel to OB strikes the other mirror at P and finally emerges parallel to OA after two reflections then theta is equal to

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 mirrors are inclined at angle theta as shown in figure. Light rays are incident parallel to one of mirrors. Light will start retracing its path after the reflection if

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.
