A horizontal rope and string are joined end-to-end at a central boundary. On the left, the medium is a thick, heavy rope. On the right, the medium is a thin, light string. An upright, crest-shaped transverse pulse travels to the right along the heavy rope toward the boundary. A horizontal arrow labeled \(v_0\) points to the right above the pulse to indicate its direction of motion. No other labels, lines, text, or axes appear.
A pulse traveling on a heavy rope toward a light string.
An upright transverse wave pulse is generated on a heavy rope that is joined to a light, thin string under the same tension. The pulse travels toward the boundary between the two media. Which of the following correctly describes the orientation of the reflected pulse and the speed of the transmitted pulse in the light string relative to its initial speed in the heavy rope?
