Ionization energy of hydrogen is

The series limit for the Paschen series of hydrogen spectrum occurs at 8205Å . Calculate. a. Ionization energy of hydrogen atom. b. Wavelength of phton that would remove the electron in the ground state of the hydrogen atom.

The frequency of light emitted, when the electron makes transition from the level of principle quantum number n = 2 to the level with n = 1 is (Take, the ionization energy of hydrogen to be 13.6eV andh =4xx 10 ^(-15) eV -s )

Ionization energy for hydrogen atom in ergs, Joules and eV respectively is :
