Photo electric effect jove physics
WebIt's the emission of electrons from a metal that has absorbed electromagnetic radiation like light over a certain frequency. A particle of light is called a photon, and when a photon has enough energy, it can actually knock an electron free. What happens is that the photon collides with the metal surface, hitting an electron. WebThe (de Broglie) pilot waves that the electrons produce are blue-shifted in the forward direction to various extents depending on the velocity of the electrons. This outgoing …
