Object $O$ is placed in front of two perpendicular mirror as shown. $I_{1}$ , $I_{2}$ & $I_{3}$ are the three images of $O$ . If $O$ moves with velocity $v$ as shown speed of $I_{3}$ will be

Options:

Answer:

Solution:

$I_{3}$ is the image after reflection from both mirrors

Its position is the point reflection of $O$ about the corner

Its velocity is $- v$ , so its speed is $v$
