Question

assertion: the refractive index of diamond is 2.42. Reason: the speed of light in air is less than the speed of light in diamond
​

Answer 1

Answer:

ANSWER

Refractive index of diamond with respect to liquid, μ=  

3

​  

 

6

​  

 

​  

=  

2

​  

 

Now, we know that critical angle is given by,

C=sin  

−1

 

μ

1

​  

 

⟹C=sin  

−1

 

2

​  

 

1

​  

=45  

o

 

And, sinC=  

μ

1

​  

⟹μ=  

sinC

1

​  

 

Hence, assertion is false but reason is true.
