In stationary wave, the velocity of particle at node is:
Correct answer: C. Zero
- A. Maximum
- B. Minimum
- C. Zero
- D. Constant
Explanation
The explanation is:At a node, the particles of the medium remain at rest. This is because at the node, the crest of one wave aligns with the trough of the other wave, causing destructive interference. The resulting net displacement is zero, and therefore the velocity of the particles at the node is also zero.

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.
