Mass bends spacetime. It's generally accepted that the photons have no mass, but they do

have momentum and energy and can cause pressure, so they have equivalent mass of p/c.

The electromagnetic radiation appears in General relativity with stress tensor, and can cause bending. But, can this be prescribed to the individual photon?

If so, how would you measure this effect if your equipment is based on interference?

Simpler question would be if there is equivalence between energy and mass, and mass causes spacetime bending, does energy cause spacetime bending?

P.S. If your answer is: No, because photons can't emit gravitons, you better elaborate.
