Question
The air column in a pipe which is closed at one end will be in resonance with a vibrating tuning fork at a frequency 260Hz. The length of the air column is :
Options
A.12.5cm
B.35.75 cm
C.31.92 cm
D.62.5cm
Solution
for fundamental frequency
n =
= l ⇒ λ 4l
n =
⇒ 260 = 
⇒ l =
= 0.3173m
n =
= l ⇒ λ 4l n =
⇒ 260 = ⇒ l =
= 0.3173mCreate a free account to view solution
