A string fixed at both ends has a linear density of 15.0 g/m, is under a tension of 425 N, and is observed to resonate with standing waves at only 160 Hz and 200 Hz, when excited by a range of frequencies from 135 Hz to 225 Hz. What is the fundamental frequency? Find the length of the string under tension. Which two harmonics were observed? What are the harmonics and their frequencies of all the other possible harmonics less than 160 Hz?
