Question

how a plane mirror forms an image ?
Describe briefly without diagram.
​

Answer 1

Answer:

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. ... If a person is reflected in a plane mirror, the image of his right hand appears to be the left hand of the image.

Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object's distance, and the same size as the object.

When we look in the mirror, we see image at the other side of the mirror.Each illuminated point on the object sends beams of light in all directions.

Light from the object arrive to the plane mirror, and each beam is reflected by the mirror according to the law of Reflection.The image is seen at the place where the continuations of the reflected beams intersect.
