Question

An open organ pipe has fundamental frequency
100 Hz. What frequency will be produced if its one
end is closed ?
A. 100, 200, 300
B. 50, 150, 250
C. 50, 100, 200, 300
D. 50, 100, 150

Answer 1

Correct Answer - B
When one end is closed
`n_1 = 1xxn_c = 50Hz`
`n_2 = 3n_c = 3xx50=150Hz`
`n_3=5n_c=5xx50=250Hz`
