In the geometric optics regime (approximation), you can call them photons, light pulses, light beams, or wave packets. You could even consider massive particles moving at 99.99% of the speed of light (neutrinos?). All of these names are the same thing in this regime. In the end, you just calculate a curve in space relative to the massive object, from which you can calculate a trajectory (position as a function of time) knowing that the light pulse always moves at c. | |
