Answer by palash jain for How does an electron absorb or emit light?
The electron absorbs energy only when it exactly matches with its energy gap you can apply here conservation of momentum. The wavelength of photon matches nearly with that of electron that's why you...

From a physical particle perspective, an electron (free or bound to an atom) cannot and does not absorb a photon. The atom absorbs the photon and takes its kinetic energy. That kinetic energy causes...

I will leave others to comment on the detailed mechanisms involved - all of which are simply mathematical models that we use to understand the process and which can be accessed at various levels of...

An atom is nothing but a bounded state of electrons and a positively charged core called nucleus. The electrons in the atom are in bound state and so their energy levels are quantized. Also, it is...

It's a common understanding that atoms emit or absorb light when the energy of the photons is equal to the the difference in the energy levels in the atom. What I don't understand is how does an...
