Please help, stuck -- Standard error in speed of sound wave...

  1. Apr 26, 2016 #1

    Not sure if this counts as "advanced physics homework" but can someone please help me here.
    I keep getting 591.1489m/s for the error in speed of sound, but the actual value of speed of sound is v=346.0425 and you obviously cant have an error larger than your actual value. (let me know if the link isnt working too)

    You can have an error bigger than the value ... for instance is you subtract two measurements.
    ##1\pm 0.1 - 0.9\pm 0.09 = 0.1\pm 0.19##

    But in your case the error on your wavelength is bigger than your wavelength (1st term under the square-root).
