First of all, it needs a source. But mostly, it needs vibrations. Depending on how strong the vibrations are determine how long the sound wave will travel.

How do sound waves travel what do sound waves need in order to travel?
sound waves bounce off of walls. they need air to travel.
Sounds need these in order to travel?
Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.
Area which wound waves are pushed apart?
A sound wave is essentially fast changing sound pressure. Longitudinal sound waves need a medium to travel through in order to exist.
Sound waves do not travel through what?
Sound wave do not travel through vaccum as it need medium to travel.
Why does a sound wave travel the slowest in a vacuum?
Sound waves don't just travel the slowest in a vacuum, they don't travel at all. The reason is that sound waves, like all mechanical waves, need a medium to travel through.
Why the sound waves could not pass through vacuum?
Sound waves need to cause vibrations in a medium in order to travel. Vibrations cannot be created in a vacuum, as there is no matter present.
Why can electromagnetic waves travel through space and not sound waves?
Sound waves need a physical material to carry them, but electromagnetic waves don't.
What wave that need a medium in order to propagate?
All sound waves, be that ultrasound or audible sound. Likewise water waves...
What do sound waves require to travel in?
Particles. They can't travel through a vacumm
What is the speed of ultrasonic waves in vacuum is equal to what is the speed of audible sound in air?
No, ultrasonic wave do not travel at all in a vacuum.
Can light be transferred across empty space?
Yes. Electromagnetic waves, like light, can travel through a vacuum, they need no medium in order to be transmitted. Unlike sound waves, which are compression waves what rely on matter in order to be transmitted.
Do sound waves need a material to travel in?
sound wave need material becuse sound wave formed by compresion and rarefaction
