| Question | Answer |
|---|---|
| The ability to do work. | Energy |
| A disturbance that transfers energy from place to place. | wave |
| The material through which a wave travels. | medium |
| Any wave that requires a medium to travel through, such as sound waves. | mechanical wave |
| Mechanical waves form when a(n) ________________ causes a medium to vibrate. | energy source |
| A repeated up-and-down or back-and-forth motion. | vibration |
| A wave in which the medium vibrates at a right angle to the direction the wave is traveling, such as a wave traveling down a rope. | transverse wave |
| A high point on a transverse wave. | crest |
| A low point on a transverse wave. | Trough |
| A wave that travels parallel to the direction the medium is vibrating. | longitudinal |
| Areas in a longitudinal wave where the particles of a medium are closer together. | compressions |
| Areas in a longitudinal wave where the particles of a medium are farther apart. | rarefactions |
| Waves such as ocean waves that occur at the boundary between two mediums. | surface waves |
| The measure of the maximum distance a wave vibrates from its rest position, or how “tall” a transverse wave is. | amplitude |
| The measure of the distance between two corresponding points on a wave; in a transverse wave, how far it is from one crest to the next crest; in a longitudinal wave, the distance between one compression and the next. | wavelength |
| The number of waves that pass a point at a given time. | frequency |
| Unit of measurement that tells the number of waves per second. | Hertz |
| How far a wave travels in a given time. | speed |
