(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If you had data from a lot of different frequencies, how could you use a slope to find the speed of sound? Explain in detail.

Given/Known: So basically we did a lab where we used 3 different tuning forks and hit them over a tube filled with water. We recorded where we heard each node and calculated what half lambda and lamda were in order to find the speed of sound.

2. Relevant equations

Speed of Sound = frequency * wavelength (lambda)

or

Speed of Sound = 331 + 0.61(T)

T = temperature in celsius (which was 20.2 in our class room)

3. The attempt at a solution

Tried taking the slope of my 3 frequencies (523.2, 1024, 2048 (Hz)) and 3 wavelengths (634.67, 316.00, 152.00 (mm) respectively) in excel. First converted the wavelengths to meters. The slope I got was -2.91. Couldn't figure out any correlation and frankly don't think that's the way to approach the problem.

Solution or any kind of tip very much appreciated. Thanks guys.
