An electron in a hydrogen atom undergoes a transition from a higher energy level to a lower energy level. The incorrect statement of the following is

Options

  1. AKinetic energy of the electron increases
  2. BVelocity of the electron increases
  3. CAngular momentum of the electron remains constant
  4. DWavelength of de-Broglie wave associated with the motion of electron decreases

Correct answer

C. Angular momentum of the electron remains constant

Step-by-step solution

As the radius of the orbit will change due to transition from a higher energy level to a lower energy level. Therefore angular momentum L =m v r will not remain constant.
