Yes. Think of a loudspeaker cone moving back and forth. When the speaker moves one direction, it compresses the air in front of it. The compression propagates away at the speed of sound. When the speaker cone moves the other direction, it generates a rarefaction, and that disturbance also moves at the speed of sound. So a "push" gives a compression wave, and a "pull" give a rarefaction wave. It works in the ground pretty much the same as it does in air.
If you mean energy then in physical waves, yes, some energy is lost to heat by friction. If you mean light waves then no. Photons do not age since they do not experience time. Some photons get absorbed but then are re-emitted. The direction may well change so the measured strength at the detection site might be less, but the total energy is still there. One other effect involves near-field levels. As photons spread out they seem to get weaker much as the ripples on a pond surrounding a pebble drop seem to weaken. This far-field drop in perceived energy does not change the total.
A deshawn wave!
When the wavelength of a wave gets higher the speed decreases. This is a studied in science.
As wavelength decreases the wave diffraction will decrease, so the curve formed will be less noticeable. The sharpness of the diffraction will decrease that you can see will lessen.
The density of air increases and then decreases as the sound wave passes.
soundyes sound travel in a straight line What Sound Looks LikeThe answer is yes and no. If you drew a line from the source of a sound to where you were when you perceived it, it would appear to be a line.However, upon further analysis (the depth of that depending on the sound you are looking at), you would see that it actually travels in a wave form, having an amplitude, frequency, wave length, period and speed.Does sound travel in a straight line?No, sound travels in a wave, therefore it does not travel in a straight line. It does travel in a line, just not a staright one
Intensity
The source that emitted the sound wave.
It is because the epicenter decreases their strenght as it is closer to it
the wave decreases.
When a wave period decreases, speed increases.
A wave.
If you drop a rock in a pond waves from the rocks splash carry energy away from the splash,if you there is something near the wave splash the object will NOT travel with the energies direction it will only go up and down
It is because the epicenter decreases their strenght as it is closer to it
No. The frequency of an EM wave depends only on the source, and cannot be altered once it has been emitted.
There's no relationship between the frequency and the medium. The frequency of a wave is determined by the source. Once the wave leaves the source and sets out on its journey, the frequency doesn't change, regardless of what kind of stuff the wave encounters and has to travel through.
When you space out the wave the amplitude decreases because when the particles are packed closer and closer each time the wave amplitude decreases.
The wave's wavelength decreases correspondingly.
