Im a little confused about how to calculate threshold energies. The threshold energy is when the energy is as low as it can possibly be and still do what it has to do, yes? So when a neutrino is detected its speed is refracted by water and so it slows down. If at the threshold the neutrino speed was c the refracted speed would be c'. How would I go about finding the threshold energy from this speed? I tried doing this by thinking about how the neutrino would scatter an electron but is there a way to find the threshold energy without doing this?
