Question
The number of possible natural oscillations of air column in a pipe closed at one end of length 85 cm whose frequencies lie below 1250 Hz are (velocity of sound = 340 ms-1)
Options
A.4
B.5
C.7
D.6
Solution
lc = 0.85 m
f0 =
= 100 Hz
fn = (2n + 1)f0 = f0, 3f0, 5f0, 7f0, 9f0, 11f0, 13f0
= 100 Hz, 300 Hz, 500 Hz, 700 Hz,
= 900 Hz, 1100 Hz
f0 =
= 100 Hzfn = (2n + 1)f0 = f0, 3f0, 5f0, 7f0, 9f0, 11f0, 13f0
= 100 Hz, 300 Hz, 500 Hz, 700 Hz,
= 900 Hz, 1100 Hz
