Waves and resonances

  1. Oct 25, 2013 #1
    Determine the values of p & c
    Use the equation logλ = p x log T + log c
    Where log T is on the x axis and logλis on the y axis.
    T is tension C is a constant and I have to find p which will be the slope of the graph plotted.
    λ was 50Hz

    I think that log 10 of 50 is 1.69897. T is the mass x 9.81 N kg-1
    T ranges from 0.4905 to 2.4525.
    How do I determine C?

    It is probably very simple for most of you but for me it is a complete mystery. The longer I struggle the more circles I complete.
    Thank you for any help or advice you can offer.

    you can rearrange your equation as


    so that will give you

    now compare it with the equation


    check for constants.

    Note:I am using "f" as frequency. In your problem you have taken it as λ
    in my solution i have taken λ as wavelength.

    Thank you, I shall try that and report back.
