| compression | a force that tends to shorten or squeeze something, decreasing its volume |
| energy | the ability to cause change or do work |
| frequency | the number of complete cycles of a wave in a given unit of time |
| medium | a substance through which energy, especially in waves, is transmitted; sound waves, for example, can travel through the medium of a solid (such as wood or steel), a liquid (such as water), or a gas (such as air) |
| pitch | the perceived tone of a sound, which is determined by the sound wave’s frequency. A sound with a high frequency and, therefore, a short wavelength has a high pitch, while a sound with low frequency and long wavelength has a low pitch. |
| sound | a form of mechanical energy produced and transmitted by vibrating matter |
| vibration | a back-and-forth motion |
| wave | a disturbance or vibration that passes through a medium (such as air, water, or solid) transmitting energy without causing a permanent change to the medium |
| wavelength | the distance between one peak or crest of a wave and the next peak or crest |
