Question
A cylindrical tube (L = 120 cm.) is in resonance with a tuning fork of frequency 330 Hz. If it is filling by water then to get resonance again, minimum length of water column is (vair = 330 m/s): -
Options
A.45 cm
B.60 cm
C.25 cm
D.20 cm
Solution
λ = 
= 1m
L = λ/4, 3λ/4, 5λ/4.... = 25cm. 75cm, 125cm
Minimum length of water column = 120-75 = 45cm
= 1mL = λ/4, 3λ/4, 5λ/4.... = 25cm. 75cm, 125cm
Minimum length of water column = 120-75 = 45cm
