Question

The refractive index of diamond is 2.47 and the speed of light in air is 3×100000000m/s. Calculate the speed of light in Diamond

Answer 1

Explanation:

The speed of light in Diamond is

1.24×10^8m/s

Answer 2

The speed of light in diamond is 1.2*10⁸ m/s.

Given - Refractive index and speed of light

Find - Speed of light in diamond

Solution - Refractive index is equal to the ratio of speed of light in air to the speed of light in medium.

meu = c/v

Keep the values in formula

v = c/meu

v = $\frac{3 \times {10}^{8} }{2.47}$

v = 1.2*10⁸ m/s

The speed of light in diamond is 1.2*10⁸ m/s.
