Answer 2

Answer:

refractive index of diamond is 2.4.

Explanation:

As,we know

refractive index is the ratio of the speed of light in vaccum divided by speed of light in medium.

here, medium is diamond.

refractive index = speed of lightin vaccum

---------------------------------------

speed of light in diamond

= 300000 km/s

___________

125000 km/s

=2.4

hence refractive index of diamond is 2.4.
