What is the dispersion relation in photons? "(Frequency momentum or etc)
A dispersion relation is the relation between the frequency omega and the wave number k.
Or, said in another way, how the phase speed of light (and hence, the index of refraction) depends on the light's frequency in that specific material/medium.
lightarrow, why restrict yourself to light? The dispersion relation are for waves, all waves, as far as I have understood it.
Ah, yes, of course, but the OP asked about photons.
haha yeah now I saw he did! ;-)
Though he asked what dispersion relation was "in general"
The dispersion relation for photons is
Thank you very much everybody. I understood it.
