The waves which propagate by the oscillation of material particles are called:
Correct answer: B. Mechanical waves
- A. Matter waves
- B. Mechanical waves
- C. Electromagnetic waves
- D. Microwaves
Explanation
Mechanical waves require a medium for propagation. e.g. sound waves, string waves, etc.Matter waves describe the relationship b/w momentum and wavelength. Matter waves are also called de Broglie waves.Electromagnetic waves don't require any medium for propagation.Microwaves are electromagnetic radiations with a frequency ranging from b/w 300MHz to 300GHz.

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.
