Correct Answer

Explanation

A characteristic of stationary waves is that they do not propagate or travel through space. Instead, they appear to be "stationary" and remain in a fixed position. In stationary waves, the energy is transferred back and forth between two waves traveling in opposite directions, resulting in areas of constructive and destructive interference. This creates distinct nodes (points of no displacement) and antinodes (points of maximum displacement) along the wave.
