Waves
Characteristics of Waves
Term | Definition |
---|---|
amplitude | the height of a transverse wave from the center to a crest or trough |
frequency | the number of waves passing a given point each second |
wave | a disturbance that transfers energy from place to place |
energy | the abiity to do work or cause change |
medium | the material through which a wave travels |
mechanical wave | a wave that requires a medium through which to travel |
vibration | a repeated back and forth or up and down motion |
transverse wave | a wave that moves the medium at right angles to the direction in which the wave travels |
crest | the highest part of a transverse wave |
trough | the lowest part of a transverse wave |
longitudinal wave | a wave that moves the medium in a direction parallel to the direction in which the wave travels |
compression | the part of a longitudinal wave where the particles of the medium are close together |
rarefaction | the part of a longitudinal wave where the particles of the medium are far apart |
wavelength | the distance between the crest of one wave and the crest of the next wave |
hertz | unit of measurement for frequency |
