The wavelength of the first overtone of a note ... - JAMB Physics 2006 Question
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 option: b
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
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
