This Experiment is designed to create various standing waves which driving by an external force.
Procedure
1. Measure the mass and length of the string.
2.
Experiment set up-1
Experiment Set up-2
3. Adjust the frequency of the function generator -> creating standing wave -> increase the wave's number of node by adjusting the frequency.
1st harmonic
2nd harmonic
3rd harmonic
4th harmonic
.
.
.
10th harmonic
4. Change tension (change hanging mass) -> measure the first 6 harmonics.
Data/Discussion
The ratio of wave speed for case 1 compared to 2 = 80.233/40.103 = 2.00
Conclusion
This experiment successfully creating accurate harmonic standing waves. Frequency and inverse wavelength showed linear relationship which increasing of frequency also increase the 1/wavelength.
