The strings on a harp are of different lengths and produce

Solution 11E The frequency of sound in the string is given by So from the above equation we can see that frequency in the string depends on the tension T , linear mass density and length L of the string. So the frequency of the sound produced by the string can be changed either by changing the length of the string or by tension of the string or by both. In the case of herp, the frequency is changed by changing the string length. But in the case of guitar, the frequency is changed by changing the tension of the string.
