| Electromagnetic radiation | a form of energy that exhibits wavelike behavior as it travels through space. |
| Electromagnetic spectrum | all the forms of electromagnetic radiation |
| Wavelength | the distance between corresponding points on adjacent waves. |
| Frequency | defined as the number of waves that pass a given point in a specific time, usually 1 second |
| Photoelectric effect | refers to the emission of electrons from a metal when light shines on the metal. |
| Quantum | the minimum quantity of energy that can be lost or gained by an atom. |
| photon | a particle of electromagnetic radiation having zero mass and carrying a quantum of energy |
| Ground state | the lowest energy state of an atom |
| Excited state | a state in which an atom has a higher potential than its ground state |
| Line-emission spectrum | a series of specific wavelengths of emitted light created when the visible portion of light from excited atoms is shined through a prism. |
| Continuous spectrum | the emission of a continuous range of frequencies of electromagnetic radiation |
