Rules for drawing ray diagrams for converging and diverging mirrors:
1. An incident ray that is parallel to the principal axis is reflected such that it passes through the principal focus (or appears to have originated at the principal focus).
2. An incident ray passing through (or heading toward) the principal focus is reflected such that it travels parallel to the principal axis.
3. An incident ray passing through (or heading toward) the centre of curvature reflects back along the same path.
