A hydrogen atom in ground state is given an energy of

10.2 \mathrm{eV}

. How many spectral lines will be emitted due to transition of electrons?

Options

A6
B3
C10
D1

Correct answer

D. 1

Step-by-step solution

Hydrogen will be in first excited state therefore it will emit one spectral line corresponding to transition b/w energy level 2 to 1
