If λ1,λ2 and λ3 are the wavelengths of the waves giving resonance with the fundamental, first and second overtones respectively of a closed organ pipe. Then the ratio of wavelengths λ1:λ2:λ3 is first and second overtones respectively of a closed organ pipe. Then the ratio of wavelengths λ1:λ2:λ3 is If λ1 λ2 and λ3 are [...]
