When photon energy is less than threshold energy

Postby Bryan Jiang 1F » Sun Apr 15, 2018 1:12 pm

I understand that when the energy of photon is less than the threshold energy, no electron will be emitted no matter the rate and how many photons of that same energy hits the electron.
My question is wanting to know where the energy of the photons go. Perhaps it dissipates as heat, but I don’t know. My follow up question would be, if I launch a stream of photons with photon energies less than the threshold energy that sequentially hit the same electron, where would all that photon energy go?

I would assume that most if not all of the energy dissipates as heat as well.

So, the energy can still be absorbed and will excite the energies of the electrons in the metal. However, because it is not great enough to emit the electrons, the energy will just dissipate throughout the metal in the form of heat for the most part.
