When an electron in Hydrogen atom revolves in stationary orbit, it
Topic: JEE PYQ
Answer: A. Full step-by-step solution below.
- Adoes not radiate light though its velocity changes
- Bdoes not radiate light and velocity remains unchanged
- Cradiates light but its velocity is unchanged
- Dradiates light with the change of energy
Correct answer: A
Solution
(a) Electrons can revolve around the nucleus in stationary orbits only which are non-radiating. Energy is radiated only when an electron jumps from an outer stationary orbit to inner stationary orbit. Velocity of electron changes while revolving in stationary orbits but energy remains constant.More Atoms PYQs
