Draw suitable diagrams to illustrate how a beam of light incident parallel to the principal axis is reflected by a convex mirror.

The diagram given below shows two parallel rays $1$ and $2$ incident on a concave mirror. Draw the reflected rays and mark the focus by the symbol $F$.

The diagram (figure) given below shows two parallel rays $1$ and $2$ incident on a convex mirror. Draw the reflected rays and mark the focus by the symbol $F$.

Complete the following diagrams in figure by drawing the reflected rays for the incident rays $1$ and $2$ if $F$ is the focus and $C$ is the centre of curvature.
