Do you mean the wavelength? Sound of higher frequencies has a shorter wavelength.
no
Yes
no
First of all, sound waves propagate away from the source, not toward it.Next, if four sound waves reached the same point at the same time, there's no reasonwhy they couldn't all have the same amplitude, frequency, speed, and wavelength.Next question ?
Your perception. All sound is the result of a medium being compressed at different levels. Speakers can produce noise, static and music all with the same action.
Sound waves are LONGITUDINAL. This means the direction of the particles is the same as the direction of the wave. Sound waves are a series of compressions (areas of high density) and rarefactions (areas of low pressure). All sound waves are caused by vibrations. They only travel if there is a medium for them to travel along, therefore there is no sound in space, or in a vacuum as it cannot travel.
All sound waves can do that.
transverse
Light waves are transverse.Sound waves may be transverse or longitudinal. Sound in gases can only be longitudinal.
Two main ways. First water waves are essentially two dimensional, i.e. on the surface of water, and sound waves are three dimensional - they (generally) spread out in all directions from the source of the sound. Second water waves are up and down undulations in the water, and are therefore at right angles to the direction of motion (transverse waves). Sound waves are compressions and rarefactions in the same direction as the direction of motion (longitudinal waves).
I think you are confusing something. Sound waves, and electromagnetic waves, are two different types of waves.
All sound waves, be that ultrasound or audible sound. Likewise water waves...
