Hint: Plane mirror has flat reflecting surface and the angle of reflection is always equal to the angle of incidence. The image formed by a plane mirror is located in front of the mirror but appears to be formed behind the plane in which the mirror lies. To find the nature of the image formed by a plane mirror. We need to study the reflection through a plane mirror.
Complete answer:
A plane mirror is a type of mirror with a flat or planar reflective surface. For the light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of the incidence is defined as the angle between the incident ray and the surface normal, which is an imaginary line perpendicular to the surface. Thus, the angle of reflection is defined as the angle between the reflected ray and the normal. A collimated beam of incident light does not spread out after reflection from a plane mirror, except in case of diffraction effect.
A plane mirror makes an image of the object in front of the mirror and these images appear to be formed behind the plane in which the mirror lies. A straight line drawn from the part of its image makes a right angle with, and is bisected by the surface of the plane mirror.
The image formed by the plane mirror is always virtual, meaning that the light rays do not actually come from the image but appear to do so, upright, and of the same shape and same size of the object it is reflecting. A virtual image is basically a copy of an object being formed.at the location for which the light rays appear to come. However,image is a laterally inverted mirror image of the object. If a person is reflected in a plane mirror the image of his left hand would appear to be the right hand of the image.
A plane mirror always forms a Virtual, behind the mirror and of the same size of the object.
So, the correct answer is option B.
Note:
Plane mirrors are the only type of optical mirror for which a real object produces an image that is virtual, erect, and of the same size of the object. The virtual objects produce a real image. The focal length of a plane mirror is defined as infinity, and its optical power is zero.
