Matter waves are:
  • A
    Electromagnetic waves
  • B
    Mechanical waves
  • C
    Either mechanical or electromagnetic waves
  • D
    Neither mechanical nor electromagnetic waves

Answer

  1. Neither mechanical nor electromagnetic waves

Explanation:

Matter waves are waves associated with every moving particle and therefore are neither mechanical nor electromagnetic waves.

These waves have

$\lambda$ = h × p

Where $\lambda$ is the wavelength, h is plank's constant, and p is the particle’s moment.

Therefore, matter waves are neither mechanical nor electromagnetic waves.
