Using a LabPro and a microphone this lab looks at the characteristics of waves created by the human voice and tuning forks. Although the wave patterns created by these types of waves will vary drastically we will compare and contrast. Frequencies, periods, amplitudes, and wavelength will be observed.
Steps:
 |
| The voice of our first participant produces a periodic wave funciton. |
 |
| Second Participants Produced Wave Function (.3s collection) |
 |
| Tuning Forks Results |
Questions/Conclusions:
1)
a. Would this be a periodic wave? Support answer with characteristics.b. How many waves are shown?c. Relate how long the probe collected data to something in everyday experience (?)d. What is the period of these waves?
e. What is the frequency?f. Calculate wavelength, assuming speed of sound to be 340 m/sg. What is the amplitude of these waves?h. What would be different about the graph if the sample were 10 times as long?
2)
Have someone else to say "AAAAA..." Compare.
3)
Collect data from the tuning fork. Compare it with the one made by human voice
4. If the same tuning fork was used to collect data for a sound that is not as loud, what would be different from the graph?
In this lab there was not much error analysis to take into account. As an introductory assignment we merely took characteristics of the results and analyzed them. The units from the amplitude of the graphs were arbitrary as we were only interested in the resulting wave patterns and characteristics.
