Parasaurolophus was a dinosaur whose distinguishing feature was ahollow crest on the head. The 1.4 m long hollow tube in the cresthad connections to the nose and throat, leading some investigatorsto hypothesize that the tube was a resonant chamber forvocalization
If you model the tube as an open-closed system, what are the firstthree resonant frequencies? (Use 350 m/s for the speed ofsound.)
Enter your answers using two significant figures in ascending orderseparated by commas.
f = _______Hz, ________Hz, ________Hz
