The fundamental tone produced by a vibrating string is 256 hz what is the frequency of the second overtone

The frequency of the nth-harmonic (corresponding to the (n-1)-th overtone) of a vibrating string is given by

where  is the fundamental frequency of the string.

In our problem,  is the fundamental frequency. The second overtone corresponds to the third harmonic, so by substituting n=3 into the previous equation, we find the frequency of the second overtone:

The answer to this is decibel
