In this experiment, sound waves are created with the use of speaker connected to a function generator. The function generator sends an oscillating current signal to the speaker which causes the speaker's diaphragm to vibrate.he material properties of the medium determine the speed with which the sound wave travels through that medium. For example, the speed of sound in water is approximately 1500m/s and through a diamond the speed can reach 12,000m/s!
