The air column in an open pipe of length 10cm is cm is set into vibration.calculate the frequency of the second overtone

1 answer

The frequency of the second overtone is 5 times the fundamental frequency.

The fundamental frequency of the air column in an open pipe is given by the formula:

f = (v/2L) * n

where v is the speed of sound, L is the length of the pipe, and n is the harmonic number.

For this problem, v = 343 m/s, L = 0.1 m, and n = 2 (for the second overtone).

Therefore, the frequency of the second overtone is:

f = (343/2*0.1) * 2 = 686 Hz
