2
Q
Threshold frequency
A
The minimum frequency of light needed to omit electrons from a certain metal surface
3
Q
Emission spectra
A
Electron in an excited state returns to a lower energy level (hot gas)
4
Q
Absorption spectra
A
An electron and a lower energy level can absorb the photon and jump to a higher energy level (cold gas?
