Question

Rules to trace an image formed by convex mirror

Answer 1

According to the graphical method, the image produced by a convex mirror can always be located by drawing a ray diagram according to four simple rules:

An incident ray which is parallel to the principal axis is reflected as if it came from the virtual focus  of the mirror.

An incident ray which is directed towards the virtual focus of the mirror is reflected parallel to the principal axis.

An incident ray which is directed towards the centre of curvature of the mirror is reflected back along its own path (since it is normally incident on the mirror).

An incident ray which strikes the mirror at its vertex $V$ is reflected such that its angle of incidence with respect to the principal axis is equal to its angle of reflection.
