Problem 4.166

A string 120 cm120 \mathrm{~cm} in length sustains a standing wave, with the points of the string at which the displacement amplitude is equal to 3.5 mm3.5 \mathrm{~mm} being separated by 15.0 cm.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. }
