प्रश्न
Express the refractive index μ of a medium in terms of the velocity of light.
उत्तर
The refractive index ‘μ’ of an optical medium is defined as the ratio between the velocity of light in vacuum divided by the velocity of light in the given optical medium. Thus,
`µ="Velocity of light in vacuum"/"Velocity of light in the given optical medium"`

In your laboratory you trace the path of light rays through a glass slab for different values of angle of incidence (∠i) and in each case measure the values of the corresponding angle of refraction (∠r) and angle of emergence (∠e). On the basis of your observations your correct conclusion is:
(a) ∠i is more than ∠r, but nearly equal to ∠e
(b) ∠i is less then ∠r, but nearly equal to ∠e
(c) ∠i is more than ∠e, but nearly equal to ∠r
(d) ∠i is less than ∠e, but nearly equal to ∠r
