because its a mechanical wave, it requires an action to be formed and that produces energy ( as a sound)

Why is a vibration of an object necessary for a sound wave to form?
sound waves cause the object to vibrate not vise versa
How does a sound wave begins?
vibration
How does vibration cause sound wave?
Vibrations alter the density of the air (or other medium) around them. They do this as a wave. When the wave reaches a person's eardrum it makes it vibrate to the rhythm of the vibration. This is conducted to the brain via an electrical impulse and we hear it as sound.
What does sound waves mean?
Sound moves by vibration. It is conducted by the vibration of matter. That vibration oscillates up and down in crests and troughs (hi's and low's). The distance or "wave length" between one crest and the next is a sound wave.
Longitudinal wave caused by vibration carried through a medium?
Sound wave.
Why is a vibration of an object necessary for a sound wave to form?
sound waves cause the object to vibrate not vise versa
Why is the vibration of an object necessary for a sound wave to form?
"Sound waves" are basically pressure waves - areas of higher and lower pressure, that propagate as a wave. You must have SOME means to create those pressure changes, and to do so quickly.
What has to happen for a sound wave to happen?
For a sound wave to be created there has to be a vibration
How does a sound wave begins?
vibration
What is the difference between a loud and soft sound?
Sound is actually a vibration in the air which travels in the form of a wave. The larger the amplitude of the wave, the "louder" the sound. the smaller the amplitude of the wave, the "softer" the sound.

What are the features of sound wave?
A sound wave is a vibration of air that travels at approximately 767mph. The higher up these vibrations go (amplitude), the louder the sound is. The closer together these vibrations are (frequency), the higher pitch the sound will be.
How does sound occur?
the lenght of the wave is depending on the vibration.
What is a sound wave made of?
A sound wave is simply a vibration in the air molecules, or the molecules of some other substance. This vibration propagates as a wave, the energy gets transferred somewhere else.
How does the vibration of a drum head cause a sound wave to form?
By passing the vibrations directly to the air in contact with its surface.
What does sound waves mean?
Sound moves by vibration. It is conducted by the vibration of matter. That vibration oscillates up and down in crests and troughs (hi's and low's). The distance or "wave length" between one crest and the next is a sound wave.
How long is a cycle in a sound wave?
A cycle in a sound wave is the time taken for one complete vibration.
