Electron Emission || for Class 12 in Hindi
Показать описание
In this Physics video in Hindi for Class 12 we explained how electrons are emitted from a metal surface. This topic is from Chapter 11 : 'Dual Nature of Radiation and Matter' for Class 12 from NCERT.
Metals have free electrons which can escape the metal if sufficient energy, in the form of heat or light or electric field, is provided.
Thermionic emission : Electron emission due to heat.
Field emission : Electron emission due to electric field.
Photo-electric emission : Electron emission due to light.
