| amplitude | the distance from a wave's resting position to it's crest or trough |
| crest | the highest point of the wave |
| frequency | the number of waves that pass a set point in a given amount of time |
| medium | the matter that waves travel through |
| resting position | the midpoint of a wave |
| trough | the lowest point of a wave |
| wave | a disturbance that carries energy through matter or space |
| wavelength | the length of one complete wave cycle |
| source of a wave | the starting point of a wave, usually started by a vibration |
| sound and light | examples of things that travel as waves |
| how particles move in a wave | up and down only, not side to side |
| How vocal cords work | by moving back and forth, causing a vibration that moves through the air as a wave |
| Light waves | unique type of wave that does not need a medium |
| 38 hertz | 38 waves have passed a set point in a second |
| length of waves | small waves have small wavelengths, large waves have long wavelengths |
