Question

Which statements are correct for an ideal stationary transverse wave on a string?

G1 Physics · Accepted Answer

A stationary wave is formed by two equal-amplitude progressive waves travelling in opposite directions. At nodes, the two component waves cancel at every instant, so the displacement remains zero. At antinodes, the local amplitude is maximum. Adjacent nodes are separated by λ/2. The two travelling components carry equal average powers in opposite directions, so the net average energy transport is zero. Therefore all four statements are correct.
