Class 12PhysicsDual Nature of Radiation and matterEinstein's Photoelectric Equation and Energy Quantum of Radiation
EasyIn the photoelectric effect,when photons of energy $h \nu$ fall on a photosensitive surface (work function $h \nu_0$),electrons are emitted from the metallic surface. It is possible to say that:
- AAll ejected electrons have the same kinetic energy equal to $h \nu - h \nu_0$.
- BThe ejected electrons have a distribution of kinetic energy from zero to $(h \nu - h \nu_0)$.
- CThe most energetic electrons have kinetic energy equal to $h \nu$.
- DAll ejected electrons have kinetic energy $h \nu_0$.
