What can you say about the relationship between the index of refraction and the wavelength of a color?

There is a dependency relationship between the refractive index of each substance and the radiation wavelength.

The refractive index in a given medium is inversely proportional to the wavelength of a color.

For example:

The rays of the red color have a wavelength greater than the rays of the blue color, therefore they have a lower refractive index and consequently a light scattering less than the blue.

Snell's law :

n₂/n₁ = v₁/v₂ =  λ₁ /λ₂

*n: (refractive index)

v: (speed of light propagation)

λ: (wavelength)
