Quantum ideas Flashcards
1
Q
threshold frequency
A
minimum frequency required for the emission of photoelectrons to occur, varied by metal
2
Q
work function
A
energy required to remove an electron from the surface of the metal
3
Q
stopping potential
A
minimum negative potential gradient of the plates at which the photoelectric current becomes zero
4
Q
electronvolt
A
energy transferred by an electron moving through a potential difference of 1 volt
5
Q
de Broglie wavelength
A
idea that all particles can exhibit wave like features, and therefore have a wavelength
6
Q
photoelectric effect
A
emission of electrons when electromagnetic radiation, such as light, hits a material
