1. The parasaurolophus was a crested, herbivorous dinosaur that lived in the Late Cretaceous Period from about 76.5 to 73 million years ago. A female parasaurolophus (which was larger than the male) had a tube on its head that was about 1.6 [m] long. The tube was hollow, open at the attachment to the head and closed at the other end. Assuming that the tube functioned as a resonance tube, what were the lowest (fundamental) and second lowest (rst harmonic) that resonated with the tube? Assume that the temperature of air was about 25 degrees Celcius (298 Kelvin)
