What Is a Sound Wave? First, let me talk about just sound in air. Of course you can have sound waves underwater (hello submarines) and even through solids. But think of air.

However, the vibration of the sound waves activated a protein pathway that helped fibroblast cells, which are important to healing, migrate to the wound.

The speed of sound is a term used to describe the speed of sound waves passing through an elastic medium. The speed varies with the medium employed (for example, sound waves move faster through ...

However until now it was not known whether sound waves also have an upper speed limit when travelling through solids or liquids.

Wave speed is measured in metres per second (m s 1). All the electromagnetic waves travel at 300,000,000 metres per second (3 × 10 8 m s 1). Sound travels at about 340 metres per second.

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Sound waves are produced by a vibrating object. Everything that makes a sound must have a part that vibrates.

Scientists are interested in the speed of sound, according to NASA, because it indicates the speed of transmitting a "small disturbance" (another way of describing a sound wave) through a gas medium.
