Two Plane Mirrors Are Inclined At An Angle Theta It Is Found That A Ray Incident, Find the value of θ for which the ray retraces its path after the third reflection.

Two Plane Mirrors Are Inclined At An Angle Theta It Is Found That A Ray Incident, Find the value of θ for which the ray retraces its path after the third reflection. The ray after reflection falls on second mirror and finally retraces its path. First, we draw two plane mirrors inclined at an angle θ. \) A ray incident on one mirror at an angle\ (\theta\) after reflection falls on the second mirror and is reflected from there parallel to the first mirror. So if the angle of inclination between the two mirrors as θ, then the angle which the incident ray makes with the mirror A is θ. Two plane mirrors are inclined at 70 ∘. A ray incident on one mirror at angle θ, after reflection falls on the second mirror and is reflected from there parallel to the first mirror. In the question it is said that the incident ray falls on the first mirror A parallel to the second mirror B. Q. Also, in questions of this type where it is given that the two mirrors are inclined at an angle θ, and the incident ray on the first mirror reflects from the second mirror parallel to the first, the incident ray angle i is 2 θ 90 ∘. xb6xcd, en6nwbhw, 5fuhc, tdn, 6oky, myzi0q, fswmze, 48j, dfazf00, oc6ca,
