ATroughs
BPhases
CNodes
DCrests
Answer & Solution
Correct answer: C. Nodes
1. Harmonic waves display more than one half wavelength on the string.
2. Those waves all have one or more points between the two end points that are not in motion.
3. The points on the string between the end points that are not moving are called the nodes.
4. Crests and troughs are the points of maximum displacement instead.
