E v *You may provide sample calculations done by hand. Using the derivative of an exponential, namely da\" du _ = u _ dx a lna dx we obtain the following for the standard deviation of the pressure amplitude P P" 1 10 my = _ x x 20 0'1: 20 n 0 Fill in Table 2. 0 Plot Power versus volume control settings. Include the error bars for the power. 5 Discussion/Conclusion: - Question 2: Do measurements 1 and 2 provide means to demonstrate the inverse square law as applied to sound waves? Briey justify your answer. No more than a page. 0 Give possible sources of errors for this experiment. I Give ways to improve the experiment.
