The waves that require medium for their propagation are known as:
Correct answer: C. Mechanical waves
- A. Electromagnetic waves
- B. De Broglie waves
- C. Mechanical waves
- D. Particle waves
- E. Matter waves
Explanation
Mechanical waves are waves that require a medium (solid, liquid, or gas) to propagate. They transfer energy through the vibration of particles in the medium.

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.
