Photoelectric effect |
The phenomenon in which electrons are liberated from a metal surface when the surface is irradiated with electromagnetic radiation of high enough frequency |
|
|
Work function energy |
Work function energy of a metal is the minimum energy required to liberate an electron from a metal surface in the photoelectric effect |
|
|
Stopping potential |
Minimum value of the retarding potential difference required to stop the photoelectron with maximum K.E. from reaching the collector |
|
|
Photon |
Discrete quantum of electromagnetic radiation energy |
|
|
Threshold frequency |
Min frequency of electromagnetic radiation incident on metal surface required for photoelectric effect to take place, that is, to eject electron from that surface |
