Question

a ray of light passes through a medium of refrective index 4/3 then the speed of light in medium is​

Answer 1

Answer:

Formula for refractive index =n=c/v

where c is the speed of light in vaccum

n is the refractive index of the medium

and v is the speed of light in that medium.

=>4/3=3×10^8/v

=>v=3×10^8×3/4

=>9×10^8/4=v

=>2.25×10^8 or 225×10^6
