Consider vibrating strings of uniform density ρ0 and tension T0.
*(a) What are the natural frequencies of a vibrating string of length L fixed at both ends?
*(b) What are the natural frequencies of a vibrating string of length H, which is fixed at x = 0 and “free” at the other end [i.e., ∂u/∂x(H, t) = 0]? Sketch a few modes of vibration as in Fig. 4.4.1.
(c) Show that the modes of vibration for the odd harmonics (i.e., n = 1, 3, 5, . . .) of part (a) are identical to modes of part (b) if H = L/2. Verify that their natural frequencies are the same. Briefly
explain using symmetry arguments.
