"Stationary waves" are so called because, in them,
Correct answer: C. There occurs no flow of energy along the wave
- A. The particles of the medium are not disturbed
- B. The particles of the medium do not execute SHM
- C. There occurs no flow of energy along the wave
- D. The interference effect can't be observed
Explanation
Energy is a wave moves because of the motion of particle of the medium. The node always remains at rest so energy cannot flow past these point.The term "stationary waves" is used because in these waves, there is no net flow of energy along the wave. Instead, the energy is reflected back and forth, creating a stable pattern.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
