Explanation / Answer

a) ionization energy = Einiinity - E1

= 0 + 6.5

ionization energy = 6.5 eV

------------------------------------------

lamda = (6.626 * 10-34 * 3 * 108) / ((6.5-2) * 1.6 * 10-19)

= 276 nm

lamda = h c / E = (6.626 * 10-34 * 3 * 108) / ((6.5-3) * 1.6 * 10-19)

= 355 nm

----------------------------------------------

both wavelengths are ultraviolet

both wavelengths are in ultraviolet part of the spectrum
