The lines on absorption atomic spectra correspond to energies needed for electrons to be excited from a lower energy level to a higher energy level. assume that the energy needed for an electron in 2p orbital in an o atom to jump to 3s orbital is 3.6*10^-19 j, what is its wavelength of the line atomic spectra in nanometer (nm)?
note: use whole numbers and 3 sig figs, or no decimal place.
