Photoelectric effect
Posted: Fri Sep 30, 2016 12:25 pm
Can someone please explain the photoelectric effect?
I understand that when the ultraviolet radiation source hits the metal with enough intensity the electrons jump off.
- the shorter the wave=higher frequency
- further, increasing intensity= increasing photons
The real question is if the threshold equals or is the same as the kinetic energy??
