By drawing a neat ray diagram, show the formation of the image of a point object placed above the principal axis of a convex mirror. Explain the construction.

Find the position, size and nature of the image formed by a spherical mirror from the following data.

$\mathrm{f}=-12 \mathrm{cm}$,

$\mathrm{u}=-36 \mathrm{cm}$,

${\mathrm{h}}_0=2 \mathrm{cm}$

An object is placed at a distance of $12 \mathrm{cm}$ from a concave mirror. The image formed is real and four times larger than the object. Calculate the distance of the image from the mirror.
