| amplitude | maximum distance the particles in a medium move from their rest positions as a longitudinal wave passes through the medium |
| intensity | amount of sound energy that passes through a square meter of space in one second |
| wavelength | distance between a point on one wave and the same point on the next wave |
| frequency | number of wavelengths that pass by a point each second |
| pitch | perception of how high or low a sound seems |
| Doppler effect | change of pitch when a sound sources moving in relation to an observer |
| interference | combination of overlapping waves, resulting in a new wave |
| resonance | increase in amplitude that occurs when an object vibrating at its natural frequency absorbs energy from a nearby object vibrating at the same frequency |
