The waves associated with particles in motion are called:
Correct answer: B. Matter waves
- A. Light waves
- B. Matter waves
- C. Electromagnetic waves
- D. Both "A" and "B"
Explanation
Option B is correct.Waves associated with microscopic particles moving at very high speed are called matter waves. Matter waves are waves associated with particles in motion. They were first proposed by Louis de Broglie in 1924. De Broglie postulated that all particles, whether they are massive or not, have a wavelength associated with them. The wavelength of matter waves is inversely proportional to the momentum of the particle. The de Broglie wavelength of a particle is given by the following equation: λ = h/p

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.
