Answer 2

Given,

Speed of light in diamond = 1.24 × 10⁸ m/s

To find,

The refractive index of the diamond.

Solution,

We can simply solve this numerical problem by using the following process.

Now,

Refractive index of a medium = (Speed of light in vaccum) / (Speed of light in the medium)

Now,

Speed of light in vaccum = 3 × 10⁸ m/s

Thus,

The refractive index of the given medium :

= [(3 × 10⁸)m/s] ÷ [(1.24×10⁸)m/s]

= (3×10⁸)/(1.24×10⁸)

= 3/1.24

≈ 2.42

(This will be considered as the final result.)

Hence, the refractive index of the diamond is approximately 2.42
