Question

A pipe 20cm long is closed at one end. Which harmonic mode of the pipe is resonantly excited by a source of 1237.5 Hz ? (sound velocity in air = 330ms-)

Answer 1

Explanation:

Which harmonic mode of the pipe is resonantly excited by a soure of 1237.5 Hz? (sound velocity in air =330ms^(-1)) Hence, 3rd harmonic node of the pipe is resonantly excited by the sourece of given frequency
