Physics - Sound Wave Question with Solution | TestHub

A pipe ${\mathrm{P}}_{\mathrm{C}}$ closed at one end and pipe ${\mathrm{P}}_{\mathrm{O}}$ open at both ends are vibrating in second overtone. They are in resonance with a given tuning fork. The ratio of the length of pipe ${\mathrm{P}}_{\mathrm{C}}$ vs ${\mathrm{P}}_{\mathrm{O}}$ is (Neglect end correction)
