Physics - Wave on String Question with Solution | TestHub

The frequencies of harmonics produced in a stretched string are integral multiples of the fundamental frequency, i.e., $n,2n,3n,\dots$

Given the fundamental frequency $n=288$ Hz.

First harmonic $=1\times 288=288$ Hz

Second harmonic $=2\times 288=576$ Hz

Third harmonic $=3\times 288=864$ Hz

Since $844$ Hz is not an integral multiple of $288$ Hz, it will not be produced as a harmonic.

Answer: 844 Hz
