the true answer is light speed
It depends on the wave. If it is electromagnetic wave it could travel at an incredible speed 300,000 km per second even through free space But mechnical waves which need badly material medium travel at different speed depending on the wave and then medium
when a wave travel through medium then sound is produced
wave speed
When a wave passes through a substance, it gets transmitted through it. The speed of the wave changes depending on the nature of the substance.
The speed at which a wave passes through water or other medium is called phase velocity.
waves are easily travel in medium.....
The speed of a wave depends on the medium it is traveling through.
The medium of an ocean wave is water.
We know that a mechanical wave requires a medium through which to travel. The source puts the energy into the medium, and it propagates. A sound wave is a good example of this, and we can contrast it with an electromagnetic wave (like light). Light can travel through a vacuum; it doesn't require a medium for its propagation.
Sound wave do not travel through vaccum as it need medium to travel.
A mechanical wave such as a sound wave requires a medium to travel through.
A Mechanical Wave is a wave that requires a medium through which to travel.
