Light rays fall on a plane mirror and form a real image. Therefore,the incident rays are:

When a beam of light is incident on a plane mirror,it is found that a real image is formed. The incident beam must be

The coordinate of the image with respect to the origin $c$ will be:

To get three images of a single object, the angle between the two plane mirrors should be (in $^{\circ}$)

An object is placed between two plane mirrors inclined at some angle to each other. If the number of images formed is $7$, then the angle of inclination is: (in $^{\circ}$)

$A$ plane mirror reflecting a ray of incident light is rotated through an angle $\theta$ about an axis through the point of incidence in the plane of the mirror perpendicular to the plane of incidence,then
