A floating maritime buoy oscillates vertically up and down as periodic water waves pass beneath it. Initially, waves with wavelength \(\lambda_0\) propagate at speed \(v_0\), resulting in a vertical position-versus-time graph for the buoy that is sinusoidal with period \(T_0\). A new set of waves then approaches the buoy with wavelength \(2\lambda_0\) propagating at the same speed \(v_0\). Which of the following best describes the buoy's new vertical position-versus-time graph compared to its initial graph?
