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
- A Kinetic energy of the electron increases
- B Velocity of the electron increases
- C Angular momentum of the electron remains constant
- D Wavelength of de-Broglie wave associated with the motion of electron decreases
Answer & Solution
Correct Answer
(C) Angular momentum of the electron remains constant
Step-by-step Solution
Detailed explanation
As the radius of the orbit will change due to transition from a higher energy level to a lower energy level. Therefore angular momentum \(\mathrm{L}=m v r\) will not remain constant.
