The radius of curvature of a spherical mirror is half of the focal length.

Rays from the Sun converge at a point $15 \, cm$ in front of a concave mirror. Where should an object be placed so that the size of its image is equal to the size of the object?

How can you distinguish between a plane mirror,a convex mirror,and a concave mirror by merely looking at the image formed in each case?

$A$ beam of light incident on a plane mirror forms a real image on reflection. The incident beam is

In a plane mirror,the distance between the image and the mirror is the same as the distance between the object and the mirror.

When an object is placed beyond the center of curvature $(C)$ in front of a concave mirror,where is the image formed and what is its nature?
