6. Compare the Theoretical values with experimental value of the length of tubes. TABLE 2 - Experimental Length of Resonance Tubes: 1st Harmonic 3rd Harmonic 5th Harmonic 7th Harmonic Exper. Theor Exp Theor Exp Theor Exp Theor Exp 1024 Hz 8.4cm 9.2cm 25.26cm 25.1cm 42.11cm 41.9cm 58.95cm 58.8cm 2048 Hz 4.21cm 4.2cm 12.63cm 12.8cm 21.05cm 21.3cm 29.47cm 29.5cm 1. For each of the "Experimental" lengths above, calculate the speed of sound using the equation in procedure step1 above. Record the results in Table 3 below. Example: f1 = (v/4L) v= f1 * 4 Llexp where "f1 = 1024 Hz" and "L 1exp " is the experimental length from the above table for 1st harmonic.
