Let two mirrors A and B be separated by a distance of $10m$. Let object O be placed at midpoint of the mirrors. Let $I_1$ be the first image in mirror A and $I_2$ be the second image in mirror B. What is the distance between $I_1$ and $I_2$?

Q. In the figure you are in a system of two vertical parallel mirrors A and B separated by distance d. A point object is placed at point O, a distance 0.2d from mirror A. Each mirror produces a first (least deep) image of the object. Then each mirror produces a second image with the object being the first image in the opposite mirror. Then each mirror produces a third image with the object being the second image in the opposite mirror, and so on - you might see hundreds of images. How deep behind mirror A are the first, second, and third images in mirror A?

Q. The distance between the object and its image in a plane mirror is $10m$. If the object is brought $2m$ closer to the mirror then the image distance from the mirror will be

Q. Two plane mirrors A and B are placed parallel to each other at a separation of $30\text{cm}$. An object is placed at a distance of $20\text{cm}$ from mirror A. What will be the distance between the images of the object formed by the mirrors?

Q. Figure shows two plane mirrors and an object $\text{O}$ placed between them. What will be distance of the first three images from the mirror $M_2$?
