Question

heyaa mate plz answer my question

What would be the refractive index of the medium A with respect to medium B, if refractive index of A is 8/7 and B is 7/6.

plz answer its urgent

Answer 1

the refractive index would be

= Refractive index of A/B

= 8/7*6/7

=48/49 = 0.97

Answer 2

let air be medium c
refractive index of a wrt b = refractive index of a wrt c× refractive index of c wrt b
refractive index of b = 8/7×6/7
=48/49=0.97
