Question

Define refractive index of a transparent medium in terms of speed of light. The velocity of light in diamond is 1,21000 km/s. What is its refractive index? (velocity of light in air = 3 x 108 m/s)​

Answer 1

Answer:

refractive index of a transparent medium is the ratio of speed of light in vaccum to speed of light in that medium. the refractive index has no unit as it is the ratio of two similiar quantities.

velocity in diamond=121000km/s ........(1)

velocity in vaccum=300000km/s.......... (2)

refractive index =V2/V1

=300000/121000=2.47
