Derive n21=v1/v2
Asked by ichigo.120106 | 18 Jan, 2021, 12:22: AM
answered-by-expert Expert Answer
When light passes from a transparent medium-1 to another transparent medium-2 ,
refractive index n21 of medium-2 with respect to medium-1 is defined as
the ratio of speed of light v1 in medium-1 to the speed of light v2 in medium-2 .
 
Hence we have , n21 = v1 / v2
