Problem
When a transverse pulse traveling along a light string reaches a junction with a much heavier string, the tension remains the same in both strings. Which statement describes the orientation of the reflected pulse on the light string?
(a) It maintains the same orientation as the incident pulse.
(b) It is inverted relative to the incident pulse.
(c) It vanishes because all energy is transmitted into the heavier string.
(d) It is shifted by 90∘ in phase relative to the incident pulse.
