A point object is placed at a distance 20 cm from the focus of a concave mirror of radius of curvature 20 cm. Find the distance (incm) of the image from the focus.

A point object is placed at a distance 20 cm from the focus of a concave mirror of radius of curvature 20 cm. Find the distance (in cm) of the image from the focus.

The distance of an object from the pole of a concave mirror is equal to its radius of curvature. The image must be:

A virtual image three times the size of the object is obtained with a concave mirror of radius of curvature 36 cm. The distance of the object from the mirror is

A virtual image three times the size of the object is obtained with a concave mirror of radius of curvature 36cm. The distance of the object from the mirror is

An object is placed at a distance of 40 cm in front of a convex mirror of radius of curvature 40 cm. List four characteristic of the image formed by the mirror.

An object of height 1cm is kept perpendicular to the principle axis of a convex mirror of radius of curvature 20cm . IF the distance of the object form the mirror is 20 cm then the distance (in cm ) between heads of the image and the object will be:
