Today in class we were performing an experiment to determine the speed of sound using a pitch-fork, a mic, a long tube, and a ti calculator.(adsbygoogle = window.adsbygoogle || []).push({});

We ended up with a very nice uniform wave-pattern on the pressure/time graph. Now that we have figured that out, we need to figure out the wavelength to complete the experiment. (using v = wavelength * frequency, frequency being the inverse of period which we can easily find)

Problem is, I'm not sure how to go about figuring out the wavelength only given the pressure/time data table. Or am I missing something completely in finding the speed of sound using given data?

Thanks in advance,
