The air column in an open pipe of length 10 cm is set into vibration. Calculate the frequency of the second overtone.(Velocity of sound in air=340ms-1)
The frequency of the second overtone is 2.82 kHz.
Frequency = (2 x Velocity of sound) / (4 x Length of pipe)
Frequency = (2 x 340) / (4 x 0.1)
Frequency = 2.82 kHz
