Question
An air column in a pipe, which is closed at one end, will be in resonance with a vibrating tuning fork of frequency 264 Hz, if the length of the column in cm is (speed of sound in air = 330 m/s)
Options
A.31.25
B.62.50
C.93.75
D.125
Solution
For closed organ pipe
where n = 1, 3, 5, .........
∴
For n = 1
cm = 31.25 cm
For n = 3 l3 = 3l1 = 93.75 cm
For n = 5 l5 = 5l1 = 156.25 cm
∴ Correct options are (a) and (c).
