Question

If the speed of light in a medium is 1.56 × 10⁸ m/s, what is the absolute refractive index of the medium​

Answer 1

Answer:

given :

speed of light in medium (v) = 1.56 × 10⁸ m/s

velocity of light in vaccum (c) = 3 × 10⁸ m/s

To fined :

absolute refractive index (n) = c

v

Calculation :

n = 3 × 10⁸

1.56 × 10⁸

n = 1.92

the absolute refractive index of the medium is 1.92

Answer 2

absolute refractive index = 1.92
