Hi, thank you for reading this.(adsbygoogle = window.adsbygoogle || []).push({});

The question is;

"A guitar string 60.0 cm in length, with a diameter of 1.40 mm and a tension of 289 N,

emits a note with a frequency of 147 Hz. Find the frequency in each of the following

situations"

d) The string produces the third harmonic of the 147 Hz fundamental frequency.

e) The string emits the third overtone of its 147 Hz fundamental.

There were 3 leading question which were just "substitute" and solve into the

equation however, the last two questions are giving me an headache.

For instance, in "D", it mentions the third harmonic of the 147 Hz, so I've began with;

3 (147Hz) = 441 Hz, then I have no idea what to do next..

Could anybody please give me some advice?
