WebSo I know that X-rays are often made by the braking radiation of electrons, and since gamma rays are higher energy photons it strikes me that it should be possible to create gamma rays the same way. Though I would imagine that you would probably need heavier charged particles or significantly higher electron energies. WebMar 6, 2024 · Photons of higher-frequency violet light have more energy than photons of lower-frequency red light, so they're more likely to knock electrons out (and liberate them with higher energy). The photons need a minimum threshold frequency (a minimum amount of energy) to free electrons and produce a photoelectric effect, known as the work function.
