Question

Image formed by a plane mirror is
A) Real and erect
B) Virtual and erects
C) Real
D) Virtual

Answer 1

Hint:Recall that a mirror that is neither curved inwards or outwards is known as the plane mirror. The plane mirrors have a flat reflective surface. The plane mirrors work on the principle of reflection of light. Plane mirrors are mostly used as looking glass. A plane mirror forms the image of the object in front of the mirror.

Complete step by step answer:
Step I:
When the rays of light strike on the surface of a plane mirror, they bounce back from the surface of the mirror. This is known as reflection of light. The light striking the plane mirror is known as incident rays and the light rays that bounce back are known as reflected rays.

Step II:
When reflection of light occurs in a plane mirror, the angle of incidence is equal to the angle of reflection. The image formed is behind the mirror. The incident ray and the reflected ray lie in the same plane. The image formed by a plane mirror is virtual and erect.

\[ \Rightarrow \]Option B is the right answer.

Note:It is to be remembered that the image formed by the plane mirror is of the same size as that of the object. Also it is formed at the same distance at which the object is placed. Also the type of image formed is helpful in determining the type of mirror without touching them. The image formed by plane mirror is laterally inverted. This means the right side seems left in the plane mirror and the left side seems right in the plane mirror.
