Model No:IE-103
Determination of Planck's Constant and Work Function of Materials by Photoelectric EffectIt was observed as early as 1905 that most metals under influence of radiation, emit electrons. This phenomenon was termed as photoelectric emission. The energy of emitted photoelectrons can be measured by simple retarding potential techniques as is done in this experiment. When a retarding potential V0 is used to measure kinetic energy of electrons Ee,
