Consider a sine wave dyz8d ;. )c(/irp zwer glrl. bmk48ug h/s/n*r9h *7tbb aa.n,k.k tgtraveling down the stretched two-part cord of Fig. 11–33. Determine a formula (a) for the ratio of the speeds of the wave in the heavy section versus that in the lighter7t,a.r9kgt b ka *b.hn 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?
