A hydrogen atom in an excited state emits a photon which has the longest wavelength of the Paschen series. Further emissions from the atom cannot include the

Options

A. longest wavelength of the Lyman series
B. second longest wavelength of the Lyman series
C. longest wavelength of the Balmer series
D. second longest wavelength of the Balmer series

Answer

D

Explanation

electron is in `3^(rd)`orbit. It may deecite to `3 to 2 , 2 to 1 , 3 to 1 ` . Therefore , the electron is in `3^(rd)` orbit. It may de-excite like `3 to 2 , 2 to 1 , 3 to 1 `. Thus the other transitions do not include `4 to 2 `
