In Fig. 3.1, the lines AB and CD are mirrors. A student traces a light ray that is reflected by both mirrors. Two optics pins, $P_1$ and $P_2$, are set on the ray that strikes mirror AB. Two further optics pins, $P_3$ and $P_4$, are set on the ray after it has been reflected by mirror CD.

A student carries out an investigation into the reflection of light from a plane mirror. She stands the mirror upright on a sheet of paper, marks the mirror’s position with a straight line called XY, removes the mirror and draws a normal at the midpoint of the line called AC, then labels the point where the normal crosses the mirror as B.
