On a marimba, the wooden bar that sounds a tone when struck vibrates in a transverse standing wave having three antinodes and two nodes. The lowest-frequency note is , produced by a bar long.
(a) Find the speed of transverse waves on the bar.
(b) A resonant pipe suspended vertically below the canter of the bar enhances the loudness of the emitted sound. If the pipe is open at the top end only, what length of the pipe is required to resonate with the bar in part (a)?
