Terms | Definitions |
|---|---|
 wave | periodic oscillation that travels through space |
| wavelength | distance between two corresponding points on a wave - |
| frequency | the number of waves passing a given point per second |
| amplitude | vertical height of a wave from the midline. Proportional to energy. |
| speed | distance per unit time (m/s) |

| threshold frequency | frequency below which electrons are not ejected in the photoelectric effect |
| photon | quantum of light energy |
| emission spectrum | specific frequencies given off by excited atoms of individual elements |
| ground state | most stable arrangement for an atom |
| excited state | high-energy state |
| orbit | specific area in which an electron can exist |
| degenerate | having the same energy |
