Answer;
Nodes
Explanation;
-One characteristic of every standing wave pattern is that there are points along the medium that appear to be standing still. These points are called nodes.
-A node is a point along a standing wave where the wave has minimum amplitude. For instance, in a vibrating guitar string, the ends of the string are nodes.
-There are other points along the medium that undergo vibrations between a large positive and large negative displacement. These are the points that undergo the maximum displacement during each vibrational cycle of the standing wave. These points are called antinodes, they are the opposite of nodes.
