I saw an answer to "how to identify a muon neutrino and electron neutrino" as being
"Weak interaction conserve not only the global lepton number, but the lepton flavor numbers as well. And that is how we identify their flavors: electron neutrinos participate in reactions that involve electrons and muon neutrinos participate in reaction that involve muons."
My question is regarding the energy of muon and electron neutrinos.
Do electron neutrinos always have less energy than muon neutrinos?
If not, if you can't identify the source of the neutrino, how can you tell if it is a muon or electron neutrino? Is the answer "by seeing if it reacts with an electron or muon"? Or can you tell by their energies?
