Momentum density of light

Webpolarized classical plane wave has a finite volume density of spin angular momentum B 2/4πω but a zero volume density of orbital angular momentum. The energy density of the wave is B 2/4π so the ratio of spin angular momentum density to energy density is 1/ ω . It is well known on the basis of experiment [13] and theory [14] and is confirmed WebIf you're looking for a pair of lightweight hiking shoes that won't weigh you down, ...
