Wave is a mechanism which transmits:

Correct answer: D. Energy

  • A. Wavelength
  • B. Amplitude
  • C. Mass
  • D. Energy

Explanation

Waves transport energy and information through a medium (or field) without net transport of mass. Thus, option D is correct.

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.
