Question

write the expression relating the refractive index of medium A with respect to medium B to the speed of light in the two media Aand B.
name the constant when medium B is vacuum.

Answer 1

refractive index of medium A / refractive index of medium b
or speed of light in medium b/ speed of light in medium aorif one is vacuum C/VC is speed of light in vacuumV- speed of light in any given medium
Case I:μAB=Refractive index of the medium A with respect to B =Speed of light in medium BSpeed of light in medium ACase II:μAvacuum=Refractive index of the medium A withrespect to vacuum =Speed of light invacuumSpeed of light in medium A =Absolute refractive index of the medium

Answer 2

Answer:

speed of light in medium B / speed of light in medium A.

when B is vacuum the refractive index becomes absolute refractive index
