Hey, I'm new to the forum- decided to ask a question that wasn't answered in school!
I get the idea that electromagnetic waves are released from photons, but I don't understand how the waves interact with anything if they don't have a mass. Also how do photons emit energy if they don't have a mass?
Maybe it's a lack of detail in my syllabus, but it seems that I kind of missed something. Just a few weeks ago our teacher explained E=mc² to us. So there I am under the impression that only something with a mass has any energy (and can therefore give out energy).
So how do photons first of all give off the energy (EM waves), and then how do the waves themselves interact with things if they don't have a mass?
Sorry if my questions seem simple, I did search the forums before posting. Any answers will be greatly appreciated!
