What is Reflection of Light - Explain its Laws 

WHAT IS REFLECTION OF LIGHT

The Reflection of light is defined as the  process of sending back of light rays that falls  on the surface of an object is known as  reflection of light. Those objects that a  having pollshed shining surface reflect more light than those object having an unpolished or dull surface. Silver metal is one of the best reflected of light............

LAWS OF REFLECTION

There are two laws of reflection which is discussed as under:

First Law of Reflection 

It states  that the incident ray , the reflected ray and the normal all lie.....



What is Refrection of Light - Explain its Laws 

WHAT IS REFRECTION OF LIGHT

This  change in direction of light when it passes from one medium to another, is known  refraction of light. It can be defined , the bending of light when it is going  from one medium to another is known refraction of light. This refraction of light takes place when the  light rays enter from glass into air or from air into glass. 

LAWS OF REFRECTION

The refraction of light on going from one medium to another takes place according to two laws these laws  are called as the laws of refraction of light. These are given below.

First Law of Refrection 

It states that the  incident ray, the refracted ray and the normal at the .....
