Question

The absolute refractive index of a medium is given by:

विकल्प

• \[n = c - v\]

• \[n = \frac{v}{c}\]

• \[n = \frac{c}{v}\]

• \[n = c \times v\]

Answer 1

The absolute refractive index is \[n = \frac{c}{v}\], where c is the speed of light in vacuum and v is the speed of light in the given medium.
