Question

velocity of light in a diamond is a 1.2 into 10 power 8 and velocity of light in vacuum is 3 into 10 power 8 of find the refractive index of diamond​

Answer 1

Answer:

refractive index of the diamond is equal to 2.5

Explanation:

given that,

velocity of light in diamond=1.2×10∧8 m/s

velocity of light in vacuum=3×10∧8m/s

we know that, refractive index of a medium

= speed of light in vacuum/speed of light in that medium

=(3×10∧8) / (1.2×10∧8)

=3 / 1.2

=2.5
