In the case of spherical mirrors,the images formed on the side of the object and images formed on the opposite side are respectively

The image formed by a convex mirror of focal length $f$ is $(1/n)$ times the size of the object. The distance of the object from the mirror is:

When an object is placed at a distance of $25 \; cm$ from a mirror,the magnification is $m_1$. The object is moved $15 \; cm$ away with respect to the earlier position,magnification becomes $m_2$. If $\frac{m_1}{m_2} = 4$,the focal length of the mirror is: (in $; cm$)

Explain the ray diagram for the image obtained by a concave mirror by considering three rays.

Provide the object and image distances,type,size,and magnification for an object placed in front of a concave spherical mirror for the cases shown in the image.

$A$ boy stands straight in front of a mirror at a distance of $30 \ cm$ away from it. He sees his erect image whose height is $\frac{1}{5}$ of his real height. The mirror he is using is
