Answer:
The refractive index can be seen as the factor by which the speed and thewavelength of the radiation are reducedwith respect to their vacuum values: the speed of light in a medium is v = c/n, and similarly the wavelength in that medium is λ = λ0/n, where λ0 is the wavelength of that light in vacuum.
