Question

Plane Mirrors: The image formed in a plane mirror is

at the same distance in front of the mirror as the object is in front of the mirror.

at a larger distance behind the mirror than the distance the object is in front of the mirror.

at the same distance behind the mirror as the object is in front of the mirror.

at a shorter distance behind the mirror than the distance the object is in front of the mirror.

a real image behind the mirror.

Answer 1

Laws of Reflection

There are two laws of reflection that are applicable to a plane mirror.

1. The angle of incidence is equal to the angle of reflection.
2. The incident ray, the reflected ray, and normal lie on the same plane.

A plane mirror is a mirror that has a flat reflecting surface without any inward or outward curve. A ray of light falling on a plane mirror is reflected at the same angle as the angle of incidence.

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.

Properties and Characteristics of a Plane Mirror

1. The image is virtual and upright.
2. The image is of the same size as that of the object, i.e., magnification = 1.
3. The distance of the object from the mirror (object distance, o) is the same as that of the image from the mirror (image distance, i). Hence, the plane mirror equation is: i = o
4. The image is laterally inverted, i.e., if the left hand is raised, it appears, as though the right hand has been raised on the image. This phenomenon is known as lateral inversion.

so answer will be at the same distance behind the mirror as the object is in front of the mirror.

which is the 3rd option.

in case of any doubt please comment thank you.
