$A$ plane mirror reflects a pencil of light to form a real image. Then the pencil of light incident on the mirror is

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

An object shaped as $L$ is placed between two parallel plane mirrors as shown. In the first seven closest images,how many laterally inverted images are formed?

If an observer is walking away from a plane mirror with a velocity of $6\;m/s$,then the velocity of the image with respect to the observer will be........$m/s$.

$A$ light bulb is placed between two plane mirrors inclined at an angle of $60^{\circ}$. The number of images formed is:

Assertion : If the angle between the two plane mirrors is $72^o$ and the object is asymmetrically placed between the two mirrors,then $5$ images of the object will be formed.
Reason : For a given system of mirrors,the total number of images formed due to successive reflection is equal to either $\frac{360^o}{\theta}$ or $\frac{360^o}{\theta} - 1$ accordingly as $\frac{360^o}{\theta}$ is odd or even respectively.
