Hi all,

I wanted to ask for an explanation on the relationship between photons
and electrons when it comes to visible light and electromagnetic
radiation.

I read that light is electromagnetic radiation and also that it is
made out of photons.

If both of these is true, is electromagnetic radiation a photon (or
photons) moving across space?

And why are the photons we receive in our eyes called electromagnetic
radiation?

Thanks
