Cherenkov radiation is produced when this value is exceeded, and this quantity divides velocity squared in the Lorentz factor.
The energy of a photon can be described as the product of its momentum and this quantity. Cherenkov radiation is produced when this value is exceeded, and this quantity divides velocity squared in the Lorentz factor. The ratio of this value in a vacuum to this value in a particular medium is the refractive index, and it is squared and multiplied by rest mass in an equation formulated by Einstein. For 10 points, name this theoretical limit on the speed of objects, which in a vacuum is approximately equal to three times ten to the eighth meters per second.
