- 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
- Electrons bounce off the plate
- Plate set up opposite the zinc plate
- Voltage put across the plates
- Number of electrons and their Ek can be measured
- Voltage put across the plates
- Fire UV light at a zinc plate
- Actuality
