Sound waves are a mechanical oscillation of pressure. It is a series of vibrations that can be heard.
Inonu Stadium located in Istanbul, Turkey is home to soccer club Besiktas JK. During a Champions League match versus Liverpool on October 24, 2007, Besiktas fans, better known as Carsi, were recorded at 132 decibels. This is the highest recorded and documented sound level at a soccer stadium, everyt…

Answer Sound travels faster in a denser medium, so sound travels most rapidly in steel. However, since sound is a longitudinal wave it is medium dependent, meaning that a medium must be present. Since a vacuum is basically defined as a lack of medium, sound will not travel at all ('No one will he…

No, there is no sound in space because there is no air. Without air sound will not travel anywhere. Sound is created by a wave moving. For a wave to move, it needs a medium. Sound travels in air or water. There is no air or water in the vacuum of space. Believe it or not...this is actually false. An…

Waves transfer energy. Energy is the ability to do work or cause change. A wave is temporary in other words the waves don't last long. Waves always travel through a medium. The mediums can be solid, liquid, or gas. All the waves that need a medium to transfer energy are called mechanical waves. Ther…

Sound is a longitudinal pressure wave of audible sound. It is a series of sound pressure waves that moves through air or other materials. These sound waves are created by the vibration of some object.

sound waves are compression waves, or longitudinal waves. sounds that we hear are actually just compressions and rarefactions of air particles, meaning the air particles move closer together for a time period then spread apart farther then they normally would rarefaction)

Sound waves bounce off the ocean floor and come back up to whatever emitted it. The time it takes for the sound wave to come back tells how far down it went.

Sound is the shape of the sound wave. Not influenced by, is. Another way of saying that is "The shape of a sound wave affects how rough or smooth that sound sounds". For example: a pure sine wave (which looks similar to a capital letter "S" lying on its side) sounds smooth whilst a pure square wa…
