A transverse wave travels in a straight line but wavers up and down. the high point is the crest and the low point is the trough
Up to a crest, then down through a trough, then back. APEX :P
Transverse Wave
Perpendicular to the direction the wave travels.
Transverse
Wave that has vibration in a direction that is perpendicular to the motion creating it
transverse wave
Transverse wave.
That sounds like the description of a transverse wave.
A transverse wave is a moving wave in which the displacement of the medium carrying the wave is perpendicular to the direction of the wave propogation. An example of a transverse wave is a string oscillating up and down.
This is a longitudinal wave or a P-wave (primary wave), called so because it travels faster than a transverse wave, which moves at right angles to the direction the wave travels.
Longitudinal wave. (as opposed to Transverse waves, where the vibrations are perpendicular to the direction of movement.)
When a compression wave travels through a medium, the particles of the medium move parallel to the direction of the wave. Compression waves are commonly called longitudinal waves.
