1) Does absorbing sample get excited when it absorbs white light in absorbing spectra experiment? Why not? 2)Why white light in absorption spectra experiment is used whereas heat is used in emission spectra experiment to provide energy? 3)Why do electrons not emit radiation when going from lower energy levels to upper? Thanks.
