please explain step by step
Photoelectron spectra were acquired from a sample of gaseous NO using He(I)
radiation, which has wavelength 58.43 nm and energy 21.22 eV. The spectrum
contained a peak for photoelectrons with speed of 1.982×106 m s´¹. Calculate the
ionization energy of these electrons. Identify the type of orbital from which they were
most likely emitted in the photoelectron spectrum for NO shown below. (Assume that
the mass of an electron is 9.10938291×10-31 kg and 1 eV = 1.602177x10-1⁹ J.)
