Question

1. Considering the length of your resonance tube (0.2275 m), whatis the lowest frequency tuning fork you could use for thisexperiment?
- In this experiment we calculated the speed of sound. Myactual value for the speed of sound was 342.309, and myexperimental value was 362.112. The diameter of the tube 0.0275mand the frequency of tuning fork used in this experiment was 384Hz. I am unsure of how to solve this problem....any help would beappreciated!

Explanation / Answer

If this was a closedtube (i.e. closed at one end), the lowest frequency wouldbe .       f = v / 4L = 342.3/ 4 * 0.2275   =    376.2 Hz . If this is an opentube, the lowest frequency would be: .     f = v / 2L =    752.3 Hz
