Can you make vedio on optoelectronic devices and it's characteristics like photodetectors, diode, led, solar cell,

Why books are also referring electrons as atoms idk.. but you mam also referred electrons as atoms. i d k how atoms can be in an energy level. An atom contains nucleus and protons, and surrounded by the cloud of electrons in diff energy level due to attractive forces. As per your views if an atom moves na the whole system will be collapsed. Em waves are only generated when an electrons moves and not an whole atom, those em waves have an frequency or wavelenght of the visible light and carry energy as discrete packet of photons.. so Please explain why all of u referring as atoms 🙃

Isnt it the same thing? We say an atom is excited when an electron gets excited to higher level!
