| wave | a disturbance that travels through water or space, carrying energy from one place to another |
| amplitude | the distance that any point on a wave has moved from its resting position |
| wavelength | the measurement of the distance between the crests and troughs in a series of waves. |
| transverse wave | a wave in which the particles vibrate at right angles to the direction of the wave |
| longitudinal wave | a wave in which the particles vibrate back and forth in the same direction as the wave is moving |
| frequency | the number of vibrations a wave has in a given time |
| pitch | the level of a sount's perceived highness or lowness |
| loudness | the perception of the amplituted of the sound wave |
| water and air | substances through wich mechanical waves move |
| trough of a wave | the lowest point of the wave |
| crest of the wave | the highest point of the wave |
| relationship between the height and the amplitude of a wave | the hight of the wave is twice the measture of its amplitude |
| movements of particles | these vibrate at right angles to the direction of the wave |
| transverse waves | the strings of musical instruments and lights |
| sound wave | an example of a longitudinal wave |
