Model Answer

A ray directed towards the principal focus of a convex mirror, after reflection, emerges parallel to the principal axis.

Explanation

This is a standard ray rule for convex mirrors (Fig. 9.4 b in the textbook). The examiner expects the key phrase "directed towards the principal focus" linked to "emerges parallel to the principal axis." One clean sentence is sufficient for 1 mark.
