Part B: All Length of air column: 5.0 m Measured Wavelength: 6.67,4,2.86,2.22 Harmonic number of measured wavelength: 3,5,7,9 Calc. wavelength: 6.67,4,2.86,2.22 % difference in wavelengths: 0,0,0,0 Answer these additional questions in three sentences MAX EACH!: What were the main sources of error in each part of the lab? Assuming the speed of sound in air is 345 m/s, what is the fundamental frequency of your closed tube. What would be the fundamental frequency of a tube open at both ends if that was the only change made? Click on the "Air Column Open at Both Ends" and find a resonance. Determine what resonance this would be and calculate its wavelength. Compare it to your measured wavelength
