 wavelength | the distance between identical points on successive waves |
| amplitude | the vertical distance from the midline of a wave to the peak or trough |
| frequency | the number of waves that pass through a particular point in 1 second |
| electromagnetic radiation | the emission and transmission of energy in the form of electromagnetic waves |
| quantum | the smallest quantity of energy that can be emitted in the form of electromagnetic radiation |
| photoelectric effect | the movement of electrons as a result of light |
| particle nature | this nature is discontinuous |
| wave nature | this nature is continuous |
| continuous spectrum | contains all wavelengths of visible light; the colors mesh with the next color |
| line spectrum | spectrum of an atom is discontinuous; this one contains only specific wavelengths of visible light that are characteristics of the species producing them |
| Heisenberg Uncertainty Principle | It is impossible to determine accurately both the momentum and the position of an electron simultaneously. Electrons are not in orbit around the nucleus in the true sense of the word. Electrons only have a probability of being located within a specified region of space. |
