| Amplitude | height of crest or trough |
| Wavelength | distance from crest to crest or compression to compression |
| Frequency | number of waves passing point in amount of time |
| Hertz | unit for frequency |
| Hz | abbreviation for Hertz |
| Speed | how far a wave travels in on unit of time |
| Formula for Speed | Wavelength x Frequency |
| Reflection | Wave hits something and bounces back |
| Refraction | bending of wave as it changes mediums |
| Diffraction | wave passes through hole and bends/spreads out |
| Example of Reflection | a puck hitting the side of an air hockey table |
| Example of Diffraction | water waves hitting rock in river |
| Example of Refraction | Broken Pencil Illusion (pencil in a glass of water) |
| Constructive Interference | 2 amplitudes added together to make 1 larger wave |
| Destructive Interference | 2 waves added together that cancel each other out |
| Resonance | matching an obects natural frequency, brought down the Tacoma Narrows Bridge |
