mirror

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 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:

A point object is placed at equal distance 3 f in front of a concave mirror, a convex mirror and plane mirror separately (event-1). Now, the distance is decreased to 1.5 f from all the three mirror (event-2). Magnitude of focal length of convex mirror and concave mirror is f . Then choose the correct options.
