How do you calculate wavelength with distance? I know that it's 4L for the first harmonic of a closed end column but what is it for an open ended column or a column with one end open, one end closed? Why does it work like that?

For a closed end we have odd harmonics.

fo, 3fo, 5fo, 7fo, 9fo, ....... fo = V/ wavelength. = V / 4L

Wavelength = 4L.


For a open end we have natural number harmonics.

fo, 2fo, 3fo, 4fo, 5fo, ....... fo = V/ wavelength. = V / 2L

Wavelength = 2L.
