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:

The absolute refractive index of the given medium is 1.92

Step-by-step explanation:

We know μ = $\frac{c}{v}$

where, μ = Refractive index of the medium

            c = Speed of light in vaccum

            v = Speed of light in the medium

Therefore, substituting the values in the formula,

=> μ = (3× 10⁸)/(1.56 × 10⁸)

       = 1.92

Therefore the refractive index of the given medium is 1.92

We know that the absolute refractive index is the refractive index of the medium with respect to vaccum. (For example in this question)

Therefore, the absolute refractive index of the given medium is 1.92
