2. An experiment was performed to determine the velocity v, of sound in air using a resonance tube with end correction c, resonating to a tuning fork of frequency f, when the length of the air column is l. Theory suggests that the relationship between these quantities is:
l = \frac{v}{4f} - c
The following data was recorded.
l/cm | 33.7 | 31.0 | 27.0 | 26.2 | 23.4 | 20.7 | 18.6 | 17.2 | 16.0
f/Hz | 252 | 278 | 315 | 325 | 364 | 410 | 456 | 495 |
a) Plot a suitable graph from which v and c could be obtained. (9 marks)
b) Use the graph to obtain the values of v and c. (8 marks)
