In most applications of concave spherical mirrors (including this activity) it is assumed that all light rays travelling parallel to the mirror's optical axis are reflected through the mirror's focal point; however, this is an approximation that applies only to light rays traveling near the mirror's optical axis. Explain why a concave spherical mirror does not reflect all light rays travelling parallel to its optical axis through its focal point.
