WebThe refractive index is a function of the frequency of the light, normally decreasing as the wavelength increases. Usually, the values at the mean wavelength of the sodium doublet, nD, i.e. 589.3 nm are quoted. Metals are characterized by a large reflectivity. On the contray, very little light is reflected by glass.
