The spring is their medium.
sound waves
Longitudinal waves occur where the motion of the medium is parallel to the waves.
Longitudinal
Sound waves, they need a medium to vibrate.A2. Earthquake waves and other mechanical waves also need a medium for their transmission.Ghv. Tsunamis are a type of mechanical wave, which is the kind of wave you're looking for.
longitudinal waves
The waves that propagate through particles of a medium are mechanical waves (aka waves of vibration).
Longitudinal waves occur where the motion of the medium is parallel to the waves.
It needs the medium to help it travel. Other examples include water waves, seismic waves, and waves traveling through a spring. Electromagnetic waves are waves that can travel through a vacuum (empty space). They don't need a medium or matter.
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
radio waves do not require a medium to travel,it can even travel through vaccum
sound waves
The spring and the mass characteristics of their transmission medium are vital to the transmission of sound and vibration waves.
Longitudinal waves occur where the motion of the medium is parallel to the waves.

Transverse Waves
Sound waves, they need a medium to vibrate.A2. Earthquake waves and other mechanical waves also need a medium for their transmission.Ghv. Tsunamis are a type of mechanical wave, which is the kind of wave you're looking for.
