With increasing frequency, at what intervals are resonance lengths found in a closed pipe?
|
|
Quarter wavelengths
|
|
|
Half wavelengths
|
|
|
Every wavelength
|
|
|
Double wavelengths

Explanation:
Detailed explanation-1: -If a sound of a certain frequency is created near a pipe filled with air, a standing sound wave can be created in the pipe. This produces resonance, which amplifies the sound produced by the original wave.
Detailed explanation-2: -The fundamental frequency of a closed pipe is 220 Hz.
Detailed explanation-3: -The fundamental frequency of a closed organ pipe is equal to the first overtone frequency of an open organ pipe. If the length of open organ pipe is 80 cm then the length of the closed organ pipe will be. No worries!
