remember
period T = wavelength/speed
and
f = 1/T = 350/wavelength
here the lowest frequency is when .14 meter = half a wavelength
so wavelength = .28 meter
lowest f = 350/.28
A pipe 0.14 meters long and capped at one end exists in a room where the speed of sound is 350 m/s. Determine the three lowest frequencies that will resonate within the tube.
[Enter the frequencies in order from lowest to highest.]
