PHOTOELECTRIC EFFECT - Part 1 | Work Function, Threshold Frequency | video in HINDI

  • In this Physics video lecture in Hindi for class 12 we discussed on Photoelectric effect and derived Einstein's photoelectric equation. Few terms we discussed here are photoelectrons, photoelectric current, work function, threshold frequency, photon etc. When radiation of sufficient frequency incidents on a metallic surface, electrons are emitted from that, known as photoelectrons. The minimum energy required to eject a free electron from the metallic surface is known as work function. The minimum frequency for which photoelectric effect occurs is known as threshold frequency.
    We also discussed on the laws of photoelectric emission :
    (1) Frequency of incident radiation ≥ Threshold frequency
    (2) Maximum kinetic energy of photoelectrons depends upon the frequency of photon (and does not depend upon intensity of radiation)
    (3) Number of photoelectrons ∝ intensity of radiation (and does not depend upon frequency)
    (4) Photoelectric emission starts as soon as radiation falls on metal surface
