**1. Homework Statement**

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. Homework 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.
