Question

If the time period of an electron in the ground state of hydrogen atom is \(1.5\times10^{-16}\) s, then the time period of the electron in the third excited state of hydrogen atom is

• A. \(2.4\times10^{-15}\) s
• B. \(9.6\times10^{-15}\) s
• C. \(6.4\times10^{-15}\) s
• D. \(4.8\times10^{-15}\) s

Hint:

In the Bohr model of the hydrogen atom, \[ \boxed{ T_n\propto n^3. } \] Remember that \[ \boxed{ \text{Third excited state } \Rightarrow n=4. } \]

Answer 1

The Correct Option is B
