Photon properties<br />
Relativistic relationship between a<br />
particle’s momentum and energy:<br />
E 2 = p 2 c 2 + m 0 2 c 4<br />
For massless (i.e. restmass = 0) particles<br />
propagating at the speed of light: E 2 = p 2 c 2<br />
For photon, E = h = ħω<br />
angular frequency ω = 2π<br />
momentum of photon = h/c = h/ = ħk<br />
wave vector k = 2π/<br />
(moving) mass of a photon: E=mc 2<br />
m = E/c 2 ; m = h/c 2 = ħω/c 2<br />
