Answer 2

Given : refractive index of medium A with respect to medium B IS 2

TO FIND :

The refractive index of medium B with respect to medium A  

As we know , the Refractive index of medium B with respect to medium A is equal to the reciprocal of the refractive index of medium A with respect to medium B

therefore , Aμ$_{B}$ = 1/Bμ$_{A}$

= 1/2 = 0.5
