N g, is related to both the refractive index, n, and its wavelength dependence. A pulse of radiation with a finite spread of wavelengths will travel at the group velocity, v g. WebChromatic Dispersion. The refractive index is the ratio between the speed of light in vacuum and a light wave’s phase velocity while traveling through a medium, such as air or glass.

WebDec 16, 2024 · The refractive index ( n) is the ratio of the velocity ( v) of light in a vacuum to the velocity in the crystal: blankn = vvacuum / vcrystal. Because light passes through a vacuum faster than through any other medium, n always has a value greater than 1. High values of n correspond to materials that transmit light slowly. WebAnd we can actually use this to figure out the velocity of light in this material. Because remember, this unknown refraction index is equal to the velocity of light in a vacuum, which is 300 million meters per second, divided by the velocity in this material, the unknown material. So we know that 1.29 is equal to the velocity of light in a vacuum.
