$A$ person runs with a speed $u$ towards a bicycle moving away from him with speed $v$. The person approaches his image in the mirror fixed at the rear of the bicycle with a speed of:

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

Two plane mirrors $A$ and $B$ are placed parallel to each other as shown in the figure. $A$ light ray is incident on mirror $A$ at an angle of $30^o$. The plane of incidence coincides with the plane of the figure. What is the maximum number of reflections (including the first one) the ray will undergo before emerging?

$A$ plane mirror is approaching you at a speed of $10\,cm/sec$. You can see your image in it. At what speed will your image approach you in $cm/sec$?

An object $O$ is placed between two parallel plane mirrors $M_1$ and $M_2$. The distance of the object from $M_1$ is $6\,cm$ and from $M_2$ is $15\,cm$. The position of the $4^{th}$ image formed by mirror $M_1$ is:

As shown in the figure,a particle is placed at $O$ in front of a plane mirror $M$. $A$ man at $P$ can move along the path $PY$ and $PY'$. Which of the following is true?
