$A$ concave mirror for face viewing has a focal length of $0.4\,m$. The distance at which you hold the mirror from your face in order to see your image upright with a magnification of $5$ is......$m$.

$A$ virtual image larger than the object can be obtained by

An object is placed at a distance of $f$ from the pole of a convex mirror of focal length $f$. Where will the image be formed?

An object is placed in front of a spherical concave mirror between the focal point $(F)$ and the center of curvature $(C)$. Its image is:

$A$ concave mirror gives an image three times as large as the object placed at a distance of $20\,cm$ from it. For the image to be real,the focal length should be........$cm$

$STATEMENT-1$: The formula connecting $u, v$ and $f$ for a spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature. because
$STATEMENT-2$: Laws of reflection are strictly valid for plane surfaces, but not for large spherical surfaces.
