Q: The ionization energy of the electron in the hydrogen atom in its ground state is 13.6 eV. The atoms are excited to higher energy levels to emit radiations of 6 wavelengths. Maximum wavelength of emitted radiation corresponds to the transition between

(a) n = 3 to n = 2 states

(b) n = 3 to n = 1 states

(c) n = 2 to n =1 states

(d) n = 4 to n = 3 states

Ans: (d)
