Standing waves on a two-dimensional surface have nodes that are:
ALines on the surface
BPoints on a line
CVolumes inside a solid
DSingle fixed corners
Answer & Solution
Correct answer: A. Lines on the surface
1. The dimensionality of a standing wave sets the shape of its nodes.
2. For one-dimensional standing waves, the nodes were points on the line.
3. For two-dimensional standing waves, the nodes are lines on the surface.
4. For three-dimensional standing waves, the nodes are two-dimensional surfaces within the volume.
