## How does refractive index of a substance is affected by optical density?

Asked by jgprmr 17th June 2017 9:18 PM

## Why does'nt  power of lens depends on refractive index of lens because more the refractive index, more strongly it will bent tge light( as high refractive index will increase the angle of refraction)
