| Number of waves per second | frequency |
| sound is this type of wave | longitudinal |
| The loudness of a sound wave depends on its | amplitude |
| the "height" from the middle of a wave to the top of crest ( peak) | amplitude |
| distance from peak of one wave to the next peak | wavelength |
| distance divided by time | speed |
| This is measured in Hertz | frequency |
| The frequency of a musical instrument is sometimes called its | pitch |
| This name is given to sounds above the human hearing range | ultrasound |
| frequency multilplied by wavelength | speed |
| low pitch means ? frequency | low |
| distance divided by speed | time |
| speed divided by wavelength | frequency |
| the time taken to make one complete wave | period |
