Tag: formation of image in a plane mirror

The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.
Hence, the statement is true.

As the image formed by a plane mirror is always virtual,upright, and of the same shape and size as the object it is reflecting.
Hence, option B is incorrect statement.

Number of images will be given by,

It should be remembered that plane mirror always form virtual and errect image and that too of same but laterally inverted.

A plane mirror always forms erect image and of same size as well.

For reflection from a plane mirror, distance between object and mirror $=$ distance between mirror and the image$=0.25m$

The size of the object in accordance with the Fresnel's displacement law is given by $\sqrt{x _1x _2}$.

A mirror that forms a virtual image of a real object is :
(a) Concave mirror: When object is placed only between pole and focus of the mirror.
(b) Convex mirror: For all positions of objects, image is virtual.
(c) Plane mirror: Image formed is virtual.

Amount of light reflected depends upon nature of material of the object, nature of the surface and smoothness of the surface. If the material is opaque for an incident light, then the total amount of incident light gets reflected. Otherwise, a part of the incident light can get transmitted.  If the surface is smooth, the reflection is more, otherwise reflected light can get scattered.
