There is likely a minimum amount of energy that can be emitted, and a minimum amount that can be received. (Bear in mind that the direction in which a photon is emitted is all directions at once, and it comes down to probability as to where it ends up landing, so if it’s weak in one direction, it’s strong the opposite way.)
There is likely a minimum amount of energy that can be emitted, and a minimum amount that can be received.
Do you mean in the physical sense of “there exists a ΔE [difference in energy between two states of a system] such that no other ΔE of any system is less energetic”? Probably, but that doesn’t mean that that energy gap is the “atom” (indivisible) of energy. (If ΔE_1 is 1 “minimum ΔE amount”, or MDEA, and ΔE_2 is 1.5 MDEA, then we can’t say that ΔE_1 corresponds to the atom of energy. For a realistic example, see relatively prime wavelengths and the corresponding energies, which cannot both be expressed as whole multiples of the same quantity of energy.)
