A string consists of three segments connected in series under a uniform tension \(T_T\): Segment 1 has linear mass density \(\mu_1 = \mu\), Segment 2 has \(\mu_2 = 4\mu\), and Segment 3 has \(\mu_3 = \frac{1}{4}\mu\). An upright wave pulse with frequency \(f_0\) and wavelength \(\lambda_0\) travels to the right in Segment 1 toward Segment 2. Which of the following correctly pairs the orientation of the pulse reflected back into Segment 1 at the boundary between Segment 1 and Segment 2 with the wavelength \(\lambda_2\) of the pulse transmitted into Segment 2?
