Question

how is the refractive index of a medium is related to light obtain an expression for refractive index of a medium with respect to another in terms of speed of light in these two medium question of class 10th please don't copy from anywhere write the answer yourself and write the answer of standard of class 10th student​

Answer 1

Answer:

The refractive index of mediumn  

m

​

 is given by

n  

m

​

=  

speed  of  light  in  medium

speed  of  light  in  air

​

=  

v

c

​

 

Let v  

1

​

   and  v  

2

​

 is the speed of light in medium 1 and medium 2 respectively.

The refractive index of medium 2 with respect to medium 1 is given by the ratio of speed of light in medium 1 and in medium 2 can be represented as:

n  

21

​

=  

v  

2

​

 

v  

1

​
