Longitudinal wave

Waves are vibrations that propagate in a medium or without medium with no propagation
along the parts of the medium itself. Longitudinal wave is a wave vibration direction parallel to
the direction of wave propagation. A series of density and strain propagate along the spring.
Density is the area where the coil spring toward each other, whereas strain is a region where the
coil spring menjahui each other. Longitudinal waves consisting of density and strain patterns.
Wavelength is the distance between successive density or strain sequence. Is meant here is the
distance of two points and the same sequence on the density or strain. Waves occur in the form
of density and renggangan. Examples of such longitudinal waves slingki / spring is pulled to the
side and then released.

 
If there is a wave that has a vibration direction perpendicular to the direction
rambatannya, whether there is a wave that has a direction of vibration in the direction of the
waves, the answer is no. Wave in question is a longitudinal wave.
To find out more clearly the scheme of longitudinal waves, let us consider the image below:
 Pictured above is a spring that vibrated at the end. If we look at the picture above we can see
that the direction of vibration in the direction of the waves, so-called longitudinal waves. A
series of density and strain propagate along the spring. Density is the area where the coil spring
toward each other, longitudinal waves consisting of density and strain patterns. Wavelength is
the distance between successive density or strain sequence. Is meant here is the distance of two
points and the same sequence on the density or strain (see example in the picture above).
Lots of examples of longitudinal waves that occur in everyday life. One example is sound waves
in air. Air as the medium of propagation of sound waves, close together and stretched along the
direction of propagation of the air. Unlike the water waves or waves of string, sound waves can
not we see the use of the eye. If someone likes listening to music, he's usually playing with a
loud volume. If you have time try to see a loudspeaker. Note the movement of the loudspeaker,
would move back and forth. It will result in vibration, and vibration that will result in air density
and the strain causing the sound waves. We now know why the source of the sound must vibrate,
because the vibration of air will form a longitudinal wave that will cause the sound waves.
Examples of longitudinalwaves:
- Waves in slinki tied at both ends stative then given fault-finding on one end

- Sound waves in air

In the transverse wave, a wave consists of 3 vertices and 2 stomach. The distance between two
nodes or two successive abdomen called the half-wavelength or ½ λ(lambda),
