Standing Wave Problem

  1. Nov 4, 2009 #1
    1. The problem statement, all variables and given/known data
    Consider standing waves that are reflecting between two identical boundaries. If the distance between the boundaries is increased by a distance delta L, what value of (delta L / lambda) will add one additional node (and antinode) to the standing wave pattern? (Assume that the wave velocity and frequency are unaffected by the change in distance.)

    2. Relevant equations

    L = (n/2)*lambda

    3. The attempt at a solution
    Isn't it just 1/2, because if we want 2 waves we do 2*(fund_freq) and in this case we want an extra wave?
