To obtain $3$ images using two plane mirrors, they should be placed at an angle of ....... $^o$.

Two mirrors $AB$ and $CD$ are arranged along two parallel lines. The maximum number of images of object $O$ that can be seen by any observer is

$A$ plane mirror is approaching you at a speed of $10\,cm/sec$. You can see your image in it. At what speed will your image approach you in $cm/sec$?

$A$ watch shows time as $3:25$ when seen through a mirror,the time appeared will be

$A$ ray is reflected in turn by three plane mirrors mutually at right angles to each other. The angle between the incident and the reflected rays is......$^o$

Assertion : The image of a virtual object due to a plane mirror is real.
Reason : If the rays seem to be converging at a point behind a plane mirror,they are reflected and they actually meet in front of the mirror.
