Measuring the speed of sound In this experiment, we Will measure the speed Of sound. The apparatus consisted of a plastic tube filled with water linked to a water container. Doctrinaires could be displaced vertically in order to change the water level.
We would teammate a tuning fork vibrate above the pipe and change the water level until the resonance waist maximum intensity-Hypothesis: The velocity of sound is 330 ms , the relationship between velocity, frequency wavelength is represented by he formula v= 1) Raw data presented Table 1 shows the frequency of the different tuning forks and the length of air needed for maximum resonance. The error on the length avgas estimated to 0. 1 CM as we repeated experimented several times. Note the error on the forks’ frequencies is a mere estimation as they’re accurately calibrated during manufacture.
