Photoelectric Effect: Li Sphere Charging and Electron Emission

Description

This lecture discusses the photoelectric effect on an isolated Li sphere with a work function of 2.49 eV, illuminated by light of frequency 6.33-10¹⁴ Hz. It explains the phenomenon of the sphere acquiring a positive potential due to emitted electrons, determines the potential at which no more electrons are emitted, and calculates the maximum fraction of emitted electrons compared to the total free electrons in the sphere.
