The light rays from an object have been reflected towards an observer from a standard flat mirror. The image observed by the observer is:

Two plane mirrors are placed parallel to each other at a distance $L$ apart. $A$ point object $O$ is placed between them at a distance $L/3$ from one mirror. Both mirrors form multiple images. The distance between any two images cannot be:

$A$ man runs towards a plane mirror at a speed of $15 \, m/s$. The speed of the image relative to the mirror is ...... $m/s$.

$A$ laser beam is incident on a plane mirror at some angle and results in a reflected beam. The mirror is now rotated by an angle $\delta$ while the direction of the incident laser beam is kept the same. The angle between the new reflected beam and the reflected beam before the mirror was rotated is

$A$ ray of light is incident normally on a plane mirror. The angle of reflection will be......$^o$

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.
