(a) State the two laws of reflection for a plane mirror.
(b) With the help of a neat, labelled ray diagram, describe an experiment using a ray box and a strip of plane mirror to verify that the angle of incidence is equal to the angle of reflection.
(c) During the experiment, the mirror is rotated anticlockwise by 10∘ about an axis perpendicular to the plane of the paper while the incident ray is kept fixed. Explain qualitatively how the direction of the reflected ray changes and give the reason for the change.
