Name: David Calderon TA: Jie Zhang Section: TH 7:35-9:25 Date: 04/24/09 SPEED OF SOUND – RESONANCE TABLE Abstract: Sound waves are longitudinal waves with same the characteristics as any other traveling longitudinal wave, such as wavelength and frequency. The speed of sound can be determined by analyzing traveling sound waves in a resonance tube with the use of equation 1: 1. v = l f Equation 2, is a known theoretical relationship between the speed of sound through air and temperature. This value is used for comparison. 2. v = (331.5 + 0.606 T ) m s , where T equals Temperature

I OBJECTIVE Determine the speed of sound through air. II PROCEDURE The equipment in this lab required the use of two tuning forks of 480 and 2048 Hz and rubber mallets to strike the tuning forks. The lab coordinator provided a resonance tube. It utilized water to vary the length sound waves could travel in the tube and a measuring tape to measure changes. The temperature of the water was found using a thermometer. A tuning fork was struck with the rubber head of the mallet and placed just about
