Hi, I'm trying to reconcile some general relativity stuff and I'm getting confused on a few topics.(adsbygoogle = window.adsbygoogle || []).push({});

Would someone be able to explain the properties of the four momentum of a photon? The way I understand it is that you take the four wave-vector of the photon and multiply it by [itex]\hbar[/itex]. The four wave-vector is simply [itex]\omega / c[/itex] as the zeroth compent and the 3-wave-vector as the spatial components. Right?

Now onto the four-momentum properties, how does the four-momentum of a photon change as it travels through spacetime? Are any components constant?

Thanks, I'll probably have follow up questions but I'd like to start with these
