Consider a sine wave travelin* 2pqm.y .fgzog down the stretched tww9z8lq gt/tq4s2x j-no-part cord of Fig. 11–33. Determine a formula (a) for the ratio of the speedsqt -zt 842g /lswxqj9n of the wave in the heavy section versus that in the lighter section, and (b) for the ratio of the wavelengths in the two sections. (The frequency is the same in both sections. Why?) (c) Is the wavelength greater in the heavier section of cord or the lighter?
