Plane Mirror

In the figure shown consider the first reflection at the plane mirror and second at the convex mirror. AB is object

A point source of light $S$ is placed in front of two large mirrors as shown. Which of the following observers will see only one image of $S$?

The reflection surface of a plane mirror is vertical. A particle is projected in a vertical plane which is also perpendicular to the mirror. The initial velocity of the particle is 10 m/s and the angle of projection is 60^o. The point of projection is at a distance 5 m from the mirror. The particle moves towards the mirror. Just before the particle touches the mirror the velocity of approach of the particle and its image is:

There are two plane mirror with reflecting surfaces facing each other. The mirrors are moving with speed $v$ away from each other. A point object is placed between the mirrors. The velocity of the $n^{\mathrm{th}}$ image will be

A light ray $I$ is incident on a plane mirror $M$. The mirror is rotated in the direction as shown in the figure by an arrow at frequency  $\frac{9}{\mathrm{\pi }}$ $\mathrm{rev} {\sec }^{-1}$. The light reflected by the mirror is received on the wall $W$ at a distance $10 \mathrm{m}$ from the axis of rotation. When the angle of incidence becomes $37°$ find the speed of the spot (a point) on the wall?

A point source of light $B$ placed at a distance $L$ in front of the centre of a mirror of width $d$ hung vertically on a wall. A man walks in front of the mirror along a line parallel to the mirror at a distance $2L$ from it as shown in figure. The greatest distance over which he can see the image of the light source in the mirror is :

How many number of images formed by two plane mirrors when the angle of incidence is $90°$?

The number of images formed by two plane mirrors when the incident angle is $45°$ is _____.

A point source of light is placed in front of a plane mirror. Which of the following is true?

A virtual and same size image as object can be obtained by-

An object $\mathrm{P}$ is kept in front of two plane mirrors as shown in the figure. The number of images formed is $\mathrm{k}$. Find out the value of $\mathrm{k}$.

Two mirrors are inclined at an angle $\theta$ as shown in the figure. Light ray is incident parallel to one of the mirrors. Light will start retracing its path after third reflection if :

An object and a plane mirror are shown in figure. Mirror is moved with velocity $V$ as shown. The velocity of image is :

Corridor figure shows an overhead view of a corridor with a plane mirror $M$ mounted at one end. A burglar $B$ sneaks along the corridor directly towards the centre of the mirror. If $d=31 \mathrm{m}$, how far (in $\mathrm{m}$) from the mirror will she be when the security guard
$S$ can first see her in the mirror?

A ray of light is incident on a plane mirror at an angle of $60°.$The angle of deviation produced by the mirror is

An object moves in front of a fixed plane mirror. The velocity of the image of the object is

Two plane mirrors are kept on a horizontal table making an angle $\theta$ with each other as shown schematically in the figure. The angle $\theta$ is such that any ray of light reflected after striking both the mirrors return parallel to its incident path. For this to happen, the value of $\theta$ should be

An object is moving towards a concave mirror of focal length $24 \mathrm{cm}$. When it is at a distance of $60 \mathrm{cm}$ from the mirror its speed is $9 \mathrm{cm} {\mathrm{s}}^{-1}$. The speed of its image at the instant is

An object moves with velocity ${\overrightarrow{v}}_0=10\hat{\mathit{i}}+j-2k$ in front of a plane mirror moving with velocity ${\overrightarrow{\mathit{V}}}_{\mathit{M}}=-5\hat{\mathit{j}}$ and mirror has its normal along $y$ axis. The velocity image is:

In the arrangement shown in figure, $S$ is a point source, $M_1$ and $M_{\mathit{2}}$ are two plane fixed mirrors inclined at an angle $\theta$ with each other. If $OS=b$, then the value of distance between two images formed.
