Problem 4.166

A string \(120 \mathrm{~cm}\) in length sustains a standing wave, with the points of the string at which the displacement amplitude is equal to \(3.5 \mathrm{~mm}\) being separated by \(15.0 \mathrm{~cm} .\) Find the maximum displacement amplitude. To which overtone do these oscillations correspond?

Reveal Answer
amax⁡=5 mm; to the third overtone. a_{\max }=5 \mathrm{~mm} ; \text { to the third overtone. }
