Given below are two statements : one is labelled as assertion A and the other is labelled as Reason R
Assertion A : The phase difference of two light wave change if they travel through different media having same
thickness, but different indices of refraction
Reason R : The wavelengths of waves are different in different media.
In the light of the above statements, choose the most appropriate answer from the options given below

Option: 1

Both A and R are correct and R is the correct explanation of A
 


Option: 2

 A is not correct but R is correct
 


Option: 3

 A is correct but R is not correct
 


Option: 4

Both A and R are correct but R is NOT the correct explanation of A

Both the statements are true
As we know speed of light in a medium

v=\frac{\mathrm{c}}{\mu} \text { or } f \lambda=\frac{\mathrm{c}}{\mu}

therefore   \lambda \propto \frac{1}{\mu}

when light will travel through two different mediums their phase difference will change

\Delta Q=\frac{2 \pi}{\lambda} \Delta x

and R is correction explanation
