TRUE      or      FALSE:
A loud sound has a greater speed than a soft sound. Yelling loud would make a sound wave travel measurably faster.

Factors Affecting Wave Speed:
The speed of a wave is dependent upon the properties of the medium through which the wave is moving. An alteration in the properties of the medium will result in a change in the speed at which the wave moves through that medium.


 
Many students are under the impression that the speed of a wave is dependent upon the properties of a wave. For instance, some believe that a more intense wave will travel faster than a less intense wave. That is, a holler will travel through air at a faster speed than a whisper. But don't be fooled! The speed at which sound waves travel through air is dependent upon the properties of the air - mainly the temperature. Only by altering the properties of a medium can the speed of sound be altered.
