When light reaches a mirror, it reflects off the surface of the mirror: the incident ray is the light going towards the mirror. the reflected ray is the light coming away from the mirror.
What happens when a light ray falls on a mirror?
Regular reflection is also known as specular reflection and occurs when a light ray falls on a surface such as a mirror. The light ray suffers a sharp reflection and almost the entire incident ray is reflected uniformly so that there is no blurriness. The angle of reflection for the different incident rays is same.
