PhysicsLAB: Speed of Sound in Air

Data: Record the resonance positions in centimeters
and the number of your tuning fork

fork #

resonance position #1 (in cm)

resonance position #2 (in cm)

Now choose the correct waveform showing the
resonance pattern you "heard" while completing
this lab.

Calculations:

Room temperature (in ºC)

Calculated speed of sound (in m/sec)

Length of a loop (in cm)

Calculated wavelength (in m)

Calculated frequency of fork (in hz)

Error Analysis:

Actual frequency stamped on fork (in hz)

Percent error
