alleryThe absolute refractive index of a medium is the ratio of:
AAngle of incidence to angle of refraction
BSpeed in the medium to speed in vacuum
CSpeed of light in vacuum to speed in the medium
DFrequency of light to wavelength
Answer & Solution
Correct answer: C. Speed of light in vacuum to speed in the medium
1. Absolute refractive index n = c / v.
2. c is the speed of light in vacuum.
3. v is the speed of light in the medium.
