When an object is placed in front of a mirror, light rays from the object strike the mirror and are reflected according to the law of reflection (angle of incidence equals angle of reflection).
In the case of parallel mirrors, the reflected rays from the first mirror encounter the second mirror and are reflected again. These secondary reflected rays then strike the first mirror, leading to another reflection.
This process of multiple reflections continues indefinitely between the parallel mirrors, with each reflection creating a new image of the object. The images formed by the first few reflections are the most distinct, while subsequent images become increasingly faint due to the loss of light intensity with each reflection.
Mathematically, the number of images produced by parallel mirrors is infinite. This is because each reflection creates a new image that is located at the same distance behind the second mirror as the object is in front of the first mirror.
As the reflections progress, the images appear to recede into the mirrors, forming a seemingly endless series of reflections. This fascinating phenomenon of infinite images is a unique characteristic of parallel mirrors and is not observed with other types of mirror configurations.
