Short answer: Both.
Long Answer: Many people would think that a tsunami is a transverse wave as they go up and down. But like all water waves a tsunami has elements of transverse wave motion and longitudinal wave motion. In a transverse wave the particles move perpendicular (at right angles) to wave direction. In a longitudinal wave the particles move parallel (in the same direction) to the wave direction. In water waves (including tsunami) the water particles move in a circular or elliptical pattern depending on the depth of the water. In the case of tsunami which can always be treated as shallow water waves, the motion is elliptical.
Note that this is only the case for non-breaking waves. As any wave (and particulalry a tsunami) breaks the pure wave behaviour will break down as the energy of the wave is transferred to the turbulent motion of the breaking wave or in some cases (as is common with tsunami) a bore, which is no longer a wave as all the wave energy has been turned into a forward moving 'wall' of water.
Earthquakes generate both transverse and longitudinal waves.
its a transverse wave
In a transverse wave, the crest corresponds to a compression in a longitudinal wave.
No, sound is a longitudinal wave, not a transverse wave.
Light is transverse in nature.
Its a transverse wave.
No, a sound wave is a longitudinal wave, not transverse.
In a transverse wave, the crest of the wave corresponds to the compression of a longitudinal wave, while the trough of the transverse wave corresponds to the rarefaction of a longitudinal wave. Both waves exhibit oscillation or vibration, but the direction in which the particles move is perpendicular to the direction of wave propagation in a transverse wave, while it is parallel in a longitudinal wave.
Yes, a sound wave is a longitudinal wave, not a transverse wave.
The vibration of the Longitudinal wave is parallel to the wave direction and the vibration is perpendicular to the direction in the transverse wave.
A sound wave is indeed a longitudinal wave as opposed to a transverse wave
The vibration of the Longitudinal wave is parallel to the wave direction and the vibration is perpendicular to the direction in the transverse wave.
