In the following properties of a wave, the one that is independent of the others in its:
Correct answer: B. Amplitude
- A. Velocity
- B. Amplitude
- C. Frequency
- D. Wavelength
Explanation
The amplitude of a wave is the maximum displacement of particles in the medium from their rest position. It represents the intensity or magnitude of the wave and is independent of velocity, frequency, and wavelength.

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.
