| Waves | A repeating disturbance or movement that transfers energy through matter or space. |
| Speed of Sound | The distance sound travels in one second. At 0 degrees Celcius, the speed of sound in air is 330 m/s. |
| Amplitude | A measure of the energy carried by a wave |
| Intensity | The amount of energy that flows through a certain area in a specific amount of time |
| Decibel | The unit for sound intensity. dB for short. The Decibel scale measures loudness. |
| Pitch | How high or low a sound seems. The pitch of a sound is related to the frequency of the sound waves |
| Doppler Effect | The change in pitch or frequency due to a moving wave source |
| Resonance | The process by which an object is made to vibrate by absorbing energy at its natural frequencies |
| Medium: | Matter in which a wave travels. |
| Sound Waves | Compressional waves that require a medium to travel in |
| Compressional waves | a wave in which the matter in the medium moves back and forth in the same direction the wave travels |
