What is the refractive index of the medium if in this medium a light wave with a frequency of 3

What is the refractive index of the medium if in this medium a light wave with a frequency of 3 * 10 ^ 14 Hz has a length of 500 nm?

Initial data: ν (vibration frequency of a light wave in the medium) = 3 * 10 ^ 14 Hz; λ (wavelength of the light wave in the medium) = 500 nm.

Reference values: C (speed of propagation of light in vacuum) = 3 * 10 ^ 8 m / s.

SI system: λ = 500 nm = 500 * 10 ^ -9 m.

The refractive index of the medium is determined by the formula: n = C / V = C / (ν * λ).

Let’s calculate: n = 3 * 10 ^ 8 / (3 * 10 ^ 14 * 500 * 10 ^ -9) = 2.

Answer: The refractive index of the medium is 2.
