    Calculate number of nodes in stationary waves

    in the first case it's the 5th harmonic, in the second case 8th, so 6 nodes and 9 nodes. http://www.wolframalpha.com/input/?i=n*%28%2816*g%29%2Fu%29%5E0.5%3D%28n%2B3%29%28%286.25*g%29%2Fu%29%5E0.5+solve+for+n+

    Calculate number of nodes in stationary waves

    Homework Statement Hi guys I have this problem that I can't solve.. Suppose to have this situation: when M=16kg the cord vibrates in one of its normal ways of oscillation. when M=6.25 we have the same frequency but 3 more nodes. How many are the nodes of the stationary wave in the first...
