Of the following properties of a wave, the one that is independent of the others is its:
Correct answer: A. Amplitude
- A. Amplitude
- B. Wavelength
- C. Speed
- D. Frequency
Explanation
Amplitude of a wave is independent whereas speed wavelength and frequency are all depend on each other via the formulaSpeed = wavelength x frequency, hence the answer will be A.

About Progressive Waves
Progressive waves transfer energy through a medium or space while particles oscillate about their equilibrium positions. The work includes amplitude, wavelength, frequency, period, phase difference, wave speed and the progressive wave equation, while distinguishing travelling waves from stationary waves, where the pattern has fixed nodes and antinodes.
