I have seen some definition like,
It is a quantity that is coming from the time translational invariance. or a quantity that should be conserved in some process.
But I am not able to understand what exactly energy is?
In STR mass even can convert into energy, that also make me so confused...
I don't know the reason. But if you just put your finger in front of one of your eye. You will see the similar effect.
Most likely it is diffraction effect. yes...
This is not the complete story, please include Lorentz Force equation. To make difference
between E and B, it is very important to remember how do they interact with some particle, that is the only way to know about them( E or B).
"Also why is only light energy released ( i.e. photons) when electrons jump?"
This particular question is very interesting.
Why is light released when electron jump? perfect one!
Possible Ans:
There are many possibilities. But why photon? more likely because other possibilities are energetically...
"Its only with these photons that have this special wave nature consisting of electric and magnetic fields ?"
By definition photons are associated with the electro-magnetic fields. There is nothing spatial about photon, in this sense.
Photons are the quanta of EM field. The speciality is that...
