Question

from the fundamental frequency on up, those frequencies that are capable of forming standing waves on a string attached at both ends are called

Explanation:

When a string is fixed at both ends, the frequencies that can form standing waves are integer multiples of the fundamental frequency. These frequencies are called harmonics. For example, if the fundamental frequency is \(f_1\), the second harmonic is \(2f_1\), the third harmonic is \(3f_1\), and so on.

Answer:

harmonics
