WebSound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.

In human physiology and … WebBoth these waves travel at different speeds in different mediums. The speed of sound in air is around 761 miles per hour or 343 meters per second. However, this speed is measured at 20 0 C. Other than this, the speed of sound in the Vacuum is 0. This is because of the absence of a medium. The speed of sound in water is about 1500 meters per second.
