REFLECTION OF LIGHT

When light rays traveling is a medium reaches the boundary of other medium, they turn back to the first medium. This phenomenon of turning back of light into the same medium after striking the boundary of other medium is called Reflection of Light.



LAWS OF REFLECTION

1. The angle of incident is equal to the angle of reflection.
2. The incident ray, the reflected ray and the normal lie on the same plane. 


REGULAR REFLECTION

When a beam pass of parallel light rays is incident on a smooth and plane surface, the reflected rays will also be parallel. This type of reflection is called Regular Reflection.



IRREGULAR REFLECTION

When a beam of parallel light rays is scattered in all directions. Therefore the parallel rays incident on the surface will reflect in different directions. This is also called Diffuse Reflection.
