Vocabulary, Unit on Waves
| Question | Answer |
|---|---|
| a disturbance that transfers energy from place to place | wave |
| a repeated back-and-forth or up-and-down motion | vibration |
| the lowest point on a transverse wave | trough |
| the highest point on a transverse wave | crest |
| a disturbance that moves the medium in a direction perpendicular to the direction of the wave | transverse wave |
| a disturbance that moves the medium in a direction parallel to the direction of the wave | longitudinal wave |
| part of a longitudinal wave where the medium particles are far apart | rarefaction |
| the part of a longitudinal wave where the medium particles are close together | compression |
| wave that requires a medium in which to transfer energy | mechanical wave |
| a material through which energy can be transferred | medium |
| the maximum distance the particles of a medium move way from their postion of rest positions as the wave passes through the medium | amplitude |
| the distance between two corresponding parts of a wave that are adjacent | wavelength |
| unit of measurement for frequency | hertz |
| the number of complete waves, wavelength, that pass a given point in a given amount of time | frequency |
| how far the wave travels in a given length of time , or its distance divided by the time it took to travel the distance | speed |
| the ability to do work | energy |
