The time period of revolution of electron in its ground state orbit in a hydrogen atom is

1.6 \times {10^{ - 16}}\mathrm{s}

The frequency of revolution of the electron in its first excited state (in Hz) is

View answer and explanation

Correct option: D

7.8 \times {10^{14}}

Option D (

7.8 \times {10^{14}}

) is correct because it's the frequency of revolution in the first excited state, calculated using the relationship between time period and orbit number.
