On the following video I show you how to calculate photon mass (at rest) which value is 0 and the apparent mass of the photon, that is the mass under relativistic effects, and that as you know it increases with velocity if this is, I think I remember, more than a 10% of "c" or speed of light. If the velocity of a particle is less than a 10% of "c" then relativistic effects are negligible and its mass is the rest mass.
They say that there is an indetermination to calculate relativistic mass of photon but this indetermination can be obviated if we calculate it from the energy of a photon which value is E=h.f, being "h" Panck's constant and "f" the frequency of a photon. What means Planck's constant is that energy is quantized. That is, a photon is released in little chuncks or quantums. "f" Is the frequency of the photon wave
Under a gravitatory field, light (visible and invisible for human eyes) varies its apparent or total mass because gravity affects its frequecy due to it cannot vary the velocity of a photon, like it does with other corps, because it always go at 300,000 km/hour.
On the video you can see the easy calculations, that only need fractions and squared roots. I am not a physicist but I am an engineer so it can be possible that my conclusions are different that those draw by them. In any case, my video serves to learn Spanish and familiarize with photon notions in a more or less ludic way. Although the video is in Spanish, calculations can be understood in whatever language.
