When an electron in hydrogen atom revolves in stationary orbit, it

A

does not radiate light though its velocity changes

B

does not radiate light and velocity remains unchanged

C

radiates light but its velocity is unchanged

D

radiates light with change of energy

Text Solution

Verified by Experts

The correct Answer is:
A
Energy of electron in stationary orbits is constant. Thus it does not radiate energy. But velocity of electron is inversely proportional to quantum number therefore its velocity changes.
