Quantum Phenomena

• How are stopping potential and Ekmax related?


  eVs=Ekmax

  where e is the charge of an electron

  where Vs is the stopping potential

  where Ekmax is the maximum kinetic energy
• What does stopping potential show?

  The potential difference required to stop the fastest electrons
• Evidence of wave properties of light

  Interference and diffraction patterns
• Evidence of particle light behaviour

  photoelectric effect
