Posted by Abhishek Sharma 3 years, 8 months ago

CBSE > Class 12 > Physics

1 answers

Parneet Kaur 3 years, 8 months ago

The absolute refractive index of a medium is defined as the ratio of speed of light in vacuum to the speed of light in a medium. n=c/v Factors affecting the absolute refractive index are: 1. Wave length of incident light 2. Temperature 3. Density of medium.
