Multiple choice

Consider the following statements regarding the waves associated with a moving electron (Matter waves):

  1. Matter waves can move with a velocity greater than that of light
  2. They can exhibit the phenomenon of interference
  3. They represent the probability of finding the electrons at different points in space
  4. They are elastic waves

  1. 1, 2 and 3

  2. 2, 3 and 4

  3. 1, 3 and 4

  4. 1, 2, 3 and 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Statement 1 is false - matter waves cannot exceed the speed of light as they are not physical waves but probability waves. Statement 2 is correct - matter waves exhibit interference patterns. Statement 3 is correct - matter waves represent probability amplitude of finding electrons at different positions. Statement 4 is false - matter waves are not elastic waves (they don't involve physical deformation of a medium). Therefore, only statements 2 and 3 are correct.
