  • The Photo Electric Effect
    • Actuality
      • Kinetic energy didn't change
      • Changing frequency did increase energy
      • Decreasing frequency gradually reduced energy until it completely stopped
      • Turning light off instantly stopped electrons
      • Turning light on instantly started electrons
        • No kettle steam effect
      • ULTRA VIOLET CATASTROPHE
    • Hypotheses
      • Increasing the amplitude of the wave would increase the current
      • Increasing the frequency would increase the energy
    • Process
      • Fire UV light at a zinc plate
        • Electrons bounce off the plate
          • Current is created
      • Plate set up opposite the zinc plate
        • Voltage put across the plates
          • Number of electrons and their Ek can be measured
