Explanation:
Light interacts with the plane mirror to form the image. There is a reflection in the plane mirror. When the light incidents on the plane mirror then the light rays get reflecting back from the mirror. The virtual image is formed of the same size as the object.
According to the law of reflection, the angle of reflection is equal to the angle of reflection.
The normal, the incident ray and the reflected ray all reflected in the same plane.
Therefore, the correct answers are as follows:
Light strikes a mirror and is then reflected off the mirror.
Light passes through a mirror to a common point behind the mirror.
Light reflects off mirrors according to the law of reflection.
