Reflection is nothing, but the mirror image of the object. When an object (P) is put before a plane mirror, the image formed is at a similar distance (P') behind the mirror as the object is in front of it. Objects are visible to us due to reflection of light from the object and then falling on our eyes. Reflection of light is a phenomenon in which light, after falling on a surface, returns into the same medium. Reflection is the idea of mapping a set of fixed points to its own isometrical identity.
