Question

The orbital frequency of an electron in the hydrogen atom is proportional to
  1. n3
  2. n3
  3. n1
  4. n0

A
n3
B
n3
C
n1
D
n0
Solution
Verified by Toppr

For Bohr's model of hydrogen atom,
mvr=nh2π
and kZe2r2=mv2r
Time period of revolution of electron =T=2πrv=4ϵ20n3h3mZ2e4n3
Thus frequency of revolving electron =1Tn3
