33 Hz is the frequency for which harmonic?- 1
- 2
- 3
- 4

| | | | |
| H1 | H2 | H3 | H4 | H5 |
ff | 2ff | 3ff | 4ff | 5ff |
| __ Hz | __ Hz | 33 Hz | __ Hz | __ Hz |
Notice that the number (2, 3, 4, or 5) is the number of antinodes OR the number of the harmonic.
To find any harmonic's frequency, multiply the fundamental frequency (ff) by the number of antinodes.
If the above is the third harmonic, then 33 Hz = 3ff (where ff is the fundamental frequency).
