Traverse wave in a string

  1. Nov 21, 2009 #1
    1. The problem statement, all variables and given/known data
    There are 8 antinodes in a string when the tension is 200 N. Find the number of antinodes when the tension on the string is increased to 800 N.


    2. Relevant equations
    n = 2*L / λ
    f = (n / 2*L)(T / μ) ^ 1/2


    3. The attempt at a solution
    This is a question I was given by my lab TA, and this subject is not treated in my text book. The two equations above I found in my lab manual, but there is no explanation as to how to use them for a problem like this!!!! The only thing I could think of is to solve the second equation for L, but I don't have most of the variables in the equation to begin with. Is there a better equation to use for this???
