When light rays from an object hit a plane mirror, they are reflected off the mirror's surface at the same angle that they hit it. These reflected rays then enter our eyes, creating the illusion of an image behind the mirror. This is known as virtual image formation.
The image formed in a plane mirror is called a virtual image because it appears to be behind the mirror, but in reality, it does not physically exist. The light rays do not actually converge at the location of the image, but our brains perceive it as if they do.
The size of the image formed in a plane mirror is the same as the size of the object being reflected. This is because the reflected rays are at the same angle as the incident rays, resulting in a one-to-one correspondence between the object and its reflection.
No, the image formed in a plane mirror cannot be magnified or diminished. The size of the image remains the same as the size of the object. However, the image can appear larger or smaller depending on the distance between the object and the mirror.
Two plane mirrors at different angles can form multiple images of a single object. The exact number of images depends on the angles between the mirrors and the object. For example, if the mirrors are perpendicular to each other, three images will be formed. If the mirrors are at a 60-degree angle, six images will be formed. However, only one virtual image will be formed from each mirror individually.
