In support of all the students who are displaced from school due to the Corona
virus. Access to physics zone and chemistry zone lessons are now available free
of charge. This will be maintained at least through August 1st 2020. Learn and be well.
Photoelectric Effect - Frequency of Incoming Light
If light is a wave... |
If light is a particle... |

|
- The amount of energy transferred to the metal would depend upon the amount of time the
light was shining on the metal.
- Any frequency of light would cause photoelectrons to be emitted, it would just take
longer for lower frequencies.
- There would be a delay between when the light strikes the surface and when
photoelectrons are ejected.
|
- The amount of energy transferred to the metal would depend only on the energy of each
particle.
- Light with too low a frequency (energy) would not ever cause photoelectrons to be
emitted.
- Light having the right frequency would cause photoelectrons to be emitted without a
delay.
