AP Physics Experiment – Measurement of Frequency of Sound Purpose To determine the frequency of a tuning fork. Procedures 1. Record the value for the frequency (f) of a standard tuning fork (Hertz). 2. Strike the tuning fork on a soft surface and position it horizontally within 1cm over the mouth of the internal cylinder. 3. Fill the cylinder three-quarters with water. Raise the cylinder until the highest pitch is perceived by an observer. Measure and record the distance from the water level to the mouth of the cylinder ( l s ) . Repeat step #2 three times. 4. Measure and record the internal diameter of the cylinder (d) in meters and the air temperature (T) in o C. 5. Calculate the velocity of sound in air using the equation v air =331m/s+(0.59m/ o C)T . 6. Calculate the frequency of the standard tuning fork using the formula f s =v/ λ where λ =4( l s + 0.4d) . Compare the calculated frequency with the known value. 7.
