The period of revolution of an electron in the ground state of hydrogen atom is ( T ). The period of revolution of the electron in the first excited state is

Options

  1. A2T
  2. B4T
  3. C1T
  4. D( 8 ~T )

Correct answer

D. ( 8 ~T )

Step-by-step solution

Time period of revolution of electron is given as T= 2 r v We know r n² and v 1 n T n³ Time period of revolution in ground state = T Time period of revolution in first excited state =T₁ 2³=8 Therefore, T T =8 T₁=8 T
