what is the index of refraction of water

Introduction:-

All of we know what is light? Light is a form of energy,which gives us sensation to look anything clearly,without light in our life we cann't imagine a second.Today I will discuss on a small niche of light and that is what is the index of refraction of water.

Explanation:-

 To go further our discussion, let us first know

 what is  reflection?

Answer:-Light ray which is travelling from a source through a medium (say air) in a straight line if it is obstructed by another medium or a surface then it bounce back from that medium or surface to the its 1st medium, this property of light is called reflection of light.

In the picture,
      MN = A plane mirror
      AO = Incident ray
      OB = Reflected ray
      OC = Normal
       O = Point of incidence

     <AOC = i = Angle of incidence

     <BOC = r = Angle of reflection
Now we will learn,

What is refraction?

Answer:- Light ray which is coming from a source through a medium in a straight line  when it enters in another medium,then it slightly change the direction of its path on the contact point of two medium, this property of light is called refraction of light.
