Consider a sine wave travelp *jgzc9ycfo x.u0g-) 7mlr1pm + coa6ing dowf1/ yardwv: 2wn the stretched two-part cord of Fig. 11–33. Determine a formula (a) for the rw:df1w2 vya/ ratio of the speeds 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?
