_{photon}= hν, where h = Planck's constant,

and E = mc

^{2}, then does hv = mc

^{2}

And if so, if c=vλ: E

_{photon}= hc/λ = mc

^{2}

Thus mass: m = h/λc ?

##E^2 = m^2c^4 + p^2 c^2##

So what is the momentum of photons since gravitation is applied?

##E^2 = m^2c^4 + p^2 c^2##

Set m=0 and you get ##E = pc##. You can solve for the momentum of the photon.

Ah. Thank youSet m=0 and you get ##E = pc##. You can solve for the momentum of the photon.
