Determine the wavelength of the radiation required to excite the electron in `Li^(+ +)` from the first to the third Bohr orbit.

A doubly ionized lithium atom is hydrogen like with atomic number 3. Find the wavelength of the radiation required to excite the electron in Li^(++) from the first to the third Bohr orbit (ionization energy of the hydrogen atom equals 13.6 eV).
