The AbrahamMinkowksi controversy regarded whether the momentum of a photon was directly or inversely proportional to this quantity, whose values at the Fraunhofer D, F and C lines can be used to calculate the Abbe number.
The Frank-Tamm formula is only valid when beta is greater than one over this quantity. The AbrahamMinkowksi controversy regarded whether the momentum of a photon was directly or inversely proportional to this quantity, whose values at the Fraunhofer D, F and C lines can be used to calculate the Abbe number. The arctangent of the (*) ratio of two values of this quantity can be used to compute Brewster's angle. This quantity can be calculated from the angle of incidence with Snell's law. For 10 points, name this ratio of the speed of light in a medium to its value in a vacuum.
