The following waves are all fixed at the ends and all the stringsare identical and are under the same amount of tension. The variables in these situations , in addition to the length L, arethe amplitude and the number of nodes. Find the wavelength and rank from greatest to least on the basis of frequency.
A) amplitude 12cm , L = 25cm and 6 nodes
B) amplitude 12cm, L=28cm and 8 nodes
C) amplitude 18cm, L= 27cm and 4 nodes
