An object is placed between two plane parallel mirrors. Why do the distant images get fainter and fainter?

If anlge between two plane mirrors is 60^@ then number of images formed are:

When an object is placed beyond centre of curvature of a concave mirror, the image is formed:

An object is placed in front of a convex mirror of focal length 30 cm.If the image formed is a quarter of the size of the object,find the position of the image.

An object is placed in front of a concave mirror of radius of curvature 30 cm at a distance of10 cm.Find the position,nature and magnification fo the image.

A and B are two protons placed in uniform electric field between two parallel plates. Which one will experience greater force?

A and B are two protons placed in uniform electric field between two parallel plates. Which one will experience greater force?

Use the mirror equation to deduce that: an object placed between the pole and focus of a concave mirror produces a virtual and enlarged image.

You have learnt in the text how Huygens of reflection and refraction. Use the same principle to deduce directly that a point object placed in front of a plane mirror produces a virtual image whose istance from the mirror is equal to the object distance from the mirror.
