The frequency of vibrations of a vibrating string is given by f = 2L where L is the length of the string, 7 is its tension, and p is its linear density.t (a) Find the rate of change of the frequency with respect to the following. (i) the length (when 7 and p are constant) X (ii) the tension (when & and p are constant) X (iii) the linear density (when _ and 7 are constant) X
