Which of the following statements about a stationary wave is NOT true?
- A. Particles between adjacent nodes vibrate out of phase with each otherCorrect
- B. Successive nodes or antinodes occur at intervals of half a wavelength
- C. Particles between adjacent nodes vibrate in phase with each other
- D. Particles between adjacent nodes have different amplitudes
Explanation
In a stationary wave, particles between two adjacent nodes vibrate IN phase (move together in the same direction at the same time), so statement A is the false (not true) statement.
