The Speed of Sound: Waves in Water

WAVES-TNZ7YW

The speed of sound varies in different mediums. For example, sound travels faster through water than it does through air.

Suppose you and a friend devise an experiment to measure the speed of sound in water. You find a copper pipe which produces a frequency of 208 Hz in the air when struck, as measured by a microphone. You repeat this same procedure underwater and measure a frequency of 907.86 Hz.
