The Photoelectric Effect Flashcards
1
Q
The Photoelectric Effect
A
When electromagnetic radiation above a threshold frequency (a high enough frequency) is incident on a metal, electrons are emitted from the surface of the metal. One electron absorbs the energy from one photon and the emitted electrons are called photoelectrons
2
Q
Threshold Frequency
A
The minimum frequency needed of electromagnetic radiation that will cause the emission of an electron from the surface of a particular metal. Measured in Hertz
3
Q
The Work Function (energy)
A
The minimum energy needed to remove a single electron from the surface of a given metal (the value is dependent on the metal)
