a low point of a wave is called a | trough |
a crest is the ______of a wave | top |
when the particles of the medium move back and forth along the direction of the wave motion, the wave is a | longitudinal wave |
when the particles of a medium are far apart , that part of the wave is called a | wave length |
compression is part of the medium where particles are___ | closer together |
a wave in which the particles of the medium are at right angles to the direction in which the wave travels is called a ____ | transverse wave |
