It varies only with the length of the pipe.


You can fit exactly 1/2 a wavelength into the pipe as a standing wave so the fundamental frequency is given by the point where the length of the pipe, #l = 1/2lambda#

This means as #v = f.lambda# the speed of sound (a constant in most cases) is found from #v = f.2l#
