(A) Let the two mirrors be $M_1$ and $M_2$ separated by distance $L$. The object $O$ is at distance $x = L/3$ from $M_1$ and $y = 2L/3$ from $M_2$.Images formed by $M_1$ are at distances $x, 2L+x, 4L+x, \dots$ behind $M_1$,i.e.,$L/3, 7L/3, 13L/3, \dots$Images formed by $M_2$ are at distances $y, 2L+y, 4L+y, \dots$ behind $M_2$,i.e.,$2L/3, 8L/3, 14L/3, \dots$The positions of images from the left mirror $M_1$ are $x_1 = L/3, x_2 = 7L/3, x_3 = 13L/3, \dots$The positions of images from the right mirror $M_2$ are $y_1 = 2L/3, y_2 = 8L/3, y_3 = 14L/3, \dots$The distances between consecutive images are $2L/3, 4L/3, 2L/3, 4L/3, \dots$Since the possible distances between adjacent images are $2L/3$ and $4L/3$,the distance $3L/2$ is not possible.

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:

What should be the angle between two plane mirrors so that whatever be the angle of incidence,the incident ray and the reflected ray from the two mirrors are parallel to each other (in $^o$)?

$A$ 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

$A$ light beam is being reflected by using two mirrors,as in a periscope used in submarines. If one of the mirrors rotates by an angle $\theta$,the reflected light will deviate from its original path by the angle
