WebbIn this video, I'll be sharing with you a fun and easy way to remember Einstein's photoelectric equation. The equation can be quite daunting at first glance,... WebbFirst your statement "In the photoelectric effect however the photon seems to give all it's momentum and energy to the electron" is not correct. In Photoelectric, the photon gives 'all' its energy to the electron, but most photon momentum goes to the more massive atom, the bind force between the electron and the atom serves as a transient of momentum. greenforest timisoara https://swheat.org
