प्रश्न
Explain the term absolute refractive index of a medium and write an expression to relate it with the speed of light in vacuum.
उत्तर
The absolute refractive index is the value of refractive index of a medium with respect to the vacuum.
`mu_B=c/v`
where
c = Speed of light in vacuum
v = Speed of light in medium B
Here, `mu_B` is the absolute refractive index of medium B.
