Answer 1

• Following are a few properties of matter waves :

  1. Matter waves are not electromagnetic in nature
  2. Matter-wave represents the probability of finding a particle in space.
  3. Matter waves are independent of the charge on the material particle.
  4. Electron microscope works on the basis of de-Broglie waves.
  5. Matter waves can propagate in a vacuum, hence they are not mechanical wave.
  6. The number of de-Broglie waves associated with nth orbital is n.
  7. The phase velocity of matter waves can be greater than the speed of light.
  8. The number of de-Broglie waves associated with the nth orbital electron is n.
