If Kinetic energy of the emitted electrons is zero when light of wavelength 686 nm. Then wavelength of radiations emitted by electron having energy 1.81 eV will be. ( Given work function of Cesium = 1.81 eV) Ultraviolet beam of wavelength 280 nm is incident on lithium surface of work function 2.5 eV. The maximum velocity of electron emitted from metal surface is November 29, 2020 Category: Chapter 11 - Dual Nature of Radiation and Matter , MTG NEET Physics , Part 2 , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
