In the shown figure two long plane mirror are kept parallel to each other with their reflecting side facing one another. A point object 'O' is situated at the distance of 20 cm from A then : calculate distance between second images formed by two mirros.

Two plane mirrors are kept parallel at 20 cm from each other. A point object O is placed exactly in between them. Calculate distance between second images formed by two mirros.

When the two plane mirror are parallel to each other, then the number of images of an object placed between them is

Two plane mirrors are placed parallel to each other at a distance L apart. A point object O placed between them, at a distance L//3 from one mirror. Both mirrors form multiple image. The distance between any two images cannot be

Two plane mirrors are placed parallel to each other. The distance between the mirrors is 10cm. An object is placed between the mirrors at a distance of 4cm from one of them, say M_(1) . What is the distance between the first time formed at M_(1) and the second image formed at M_(2) ?

Two plane mirrors are kept such that angle between their reflecting surfaces is 40^(@) . A point object is kept symmetrically with respect to the mirrors. The total number of images formed by one mirror is :

In the shown figure M_(1) and M_(2) are two concave mirrors of the same focal length 10 cm . AB and CD are their pricipal axes respectively. A point object O is kept on the line AB at a distance 15 cm from M_(1) . The distance between the mirror is 20 cm . Considering two successive reflections first on M_(1) and then on M_(2) . The distance of final image from the line AB is:

Two plane mirrors are plaved parallel to each other and 40 cm apart. An a object is placed 10 cm from one mirror .What is the distance from the object to the image for each of the five images that are closest to the object?

There are two plane mirror with reflecting suface faciing each other.The mirrors are moving with speed v away form each other .A point object is placed between the mirrors.The velocity of the n-th image will be

A point object is placed as shown. The two pieces are of the same lens of focal length 10 cm. Find the distance (in cm) between the two images formed by two pieces of the lens.

The figure shows two plane mirrors parallel to each other and an object O placed between them. Then , the distances of the first three images from the mirror M_2 will be (in cm)
