Question

An electron transition occurs from n = 4 to n=2 energy level in hydrogen atom. Find the wavelength of emitted radiation, if the energy of the electron in ground state is -13.6eV. To which series does this spectral line belongs ​

Answer 1

please mark me as brainlist

When an electron transit from n = 4 to n = 2 then emitted line in spectrum will be second line of Balmer series.

Balmer series corresponds to the transitions n

2

→2.

The fist line corresponds to the transition 3→2.

The second line corresponds to the transition 4→2.
