Web20 feb. 2024 · We define the index of refraction n of a material to be (25.3.3) n = c v, where v is the observed speed of light in the material. Since the speed of light is always less than c in matter and equals c only in a vacuum, the index of refraction is always greater than or equal to one. That is, n > 1. WebThe refractive index can be seen as the factor by which the speed and the wavelengthof the radiation are reduced with 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 λ0is the wavelength of that light in vacuum.
