GELOMBANG LONGITUDINAL

wave which has a vibration direction perpendicular to the direction rambatannya, whether there is a wave that has a vibration direction of the direction of the waves, l. A series of density and strain propagating along the spring. Density is the area where the coil spring toward each other, while the strain is the region where the coil spring menjahui each other. If you analyze the transversal wave has a pattern of peaks and valleys, the longitudinal wave consists of a pattern of density and strain. Wavelength is the distance between successive density or strain, respectively. What is meant here is the distance from the same two points and a sequence of density or strain

There are so many examples of longitudinal waves that occur in everyday life. One example is sound waves in air. Air as the medium of sound wave propagation, docked and stretched along the direction of wave propagation in the air. Unlike the water waves or waves of the rope, the sound waves we can not see using the eye. If someone likes listening to music, he usually play with the volume loud, :-). If you have time try to notice a loudspeaker. Notice the movement of the loudspeaker, it must move back and forth. It will produce vibrations, and vibrations that would result in air density and the strain causing the sound waves. Now we have to know why the sound source must be vibrated, since the vibration of air will form a longitudinal wave that will generate sound waves.


Examples of longitudinal waves:
- Wave at both ends tied slinki on stative then given tease on one end
- Waves of sound in air
The formula of the second wave include the following:
V V = λ f = λ / T
'
Description:
T = wave period
V = wave propagation speed (m / s)
λ = wavelength (m)
f = wave frequen

Ungu – Dirimu Satu

i will always love you kekasihku

dalam hidupku hanya dirimu satu

i will always need you cintaku

selamanya takkan pernah terganti

ku mau menjadi yang terakhir untukmu

ku mau menjadi mimpi indahmu

cintai aku dengan hatimu

seperti aku mencintaimu

sayangi aku dengan kasihmu

seperti aku menyayangimu

i will be the last for you

and you will be the last for me

i will be the last for you

and you will be the last for me
