Problem
(a) A student fixes a plane mirror upright on a drawing board and uses pins P and Q to mark an incident ray. After locating the image points, she places pins R and S to mark the reflected ray but finds that the two sets of pins cannot be seen in a single straight line when viewed from above. What does this tell you about the positions of the incident ray, reflected ray and normal?
(b) Suggest two specific adjustments she should make so that the first law of reflection is satisfied.
