The wavelength of the first overtone of a note in a closed pipe of length 33 cm is?
-
A.
33 cm -
B.
44 cm -
C.
22 cm -
D.
17 cm
Correct Answer: Option B
Explanation
In a closed tube, the fundamental note occurs when the length of the tube l = (λ)/4,
the first over tone occurs when the length of the tube l = (3)/4λ.
λ = (4)/3 l = (4)/3 x (33)/T = 44 cm
