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

What can be the largest distance of an image of a real object from a convex mirror of radius of curvature $10\,cm$?

The focal length of a convex mirror is $20\, cm$. Its radius of curvature will be.....$cm$.

$A$ concave mirror of focal length $10 \, cm$ is immersed in water $(\mu = 4/3)$. The new focal length will be ...... $cm$.

$A$ square of side $3 \ cm$ is placed at a distance of $25 \ cm$ from a concave mirror of focal length $10 \ cm$. The center of the square is on the axis of the mirror and the plane is perpendicular to the axis. The area enclosed by the image of the square is ........ $cm^2$.

The graph between $u$ and $v$ for a convex mirror is
