    Hi
    I am currently studying standing waves and harmonics, and am of the understanding that a high mass per unit length decreases the wave frequency on the string. Why would this happen? Does a high mass per unit length equate to a high density ( generally) and dont mechanical waves, such as those along a string, travel faster in denser media?

    Yeah, pretty much. You need to take the square root of the mass (divided by the mean of the wave frequency), then you take the exponential and you divide by the sum of the amplitude of each wave peak and then you end up with something that's proportionate to the square of the initial equation

    Thanks for the reply but you've kinda lost me here... I was just wondering why increasing the mass per unit length does not increase the frequency?
