In lecture, we were given the formula f=nf1 as a trick to help solve standing wave questions faster.

It was said that f is the harmonic frequency and f1 is the fundamental frequency.

Would you be able be able to explain the difference between the harmonic frequency and fundamental frequency? Would those values be explicitly given or do we need to be able to interpret them from a question stem?

Thanks!

Hi Gilbert,

In the equation is fn=nf1, f1 refers to the frequency of a standing wave specifically when n=1 (also called the "fundamental frequency").

fn refers to the frequency at harmonic # n

So you can use the equation to find the frequency for any harmonic number if you know the fundamental frequency which is often given in MCAT questions.
