You are saying that EM waves do not have mass.
But let's say we have a medium and a wave is absorbed. Doesn't it mean that the wave must put pressure on the particle in order to be absorbed? i mean, if you have electric and magnetic fields in a EM wave, then electric field would cause some...
I am trying to understand light, it is so weird. Light is not an electromagnetic wave, since it has different speed in different mediums. Light does not have mass (the mass that can be derived from the energy is not a real mass), so its not a particle either. What is it?
Back to my original...
What is the relationship between photon and electromagnetic wave?

What is the charge then? the photon is the one who provides interaction between charges, but what is it in the charge that makes photon "move"?
Can I assume that field lines are moving photons?
Are field lines like the wind and photons like the moving sand? Only to move each grain of sand you...
Can I assume that anything with high enough speed will generate electromagnetic wave? Photons are not charged. But maybe because they move fast enough, they generate vortex electric field, since this field is changing, then you have a corresponding magnetic field with it, so you have an...
lets say my battery died. so both terminals are 12V. how can I recreate the potential difference? What do I physically need to do to start the movement of charges? Just apply a current? but then, as I apply current, some charge will move back to the first terminal, and I will not get a high...
in a battery what pushes the charge from one terminal to another at the very first step when both terminals have the same electric potential? how can i start the loop of current?
