If atom is hit by a photon that is the precise wavelength/energy like one of its absorption lines, will it put the electron inside the atom to a higher excited orbital level, in that short timeframe before the electron falls down to lower energy level,is that atom less absorptive at that photon wavelength?
To further expand my question, if truly does the absorption line disappear, do lower absorption lines below the one that was hit disappear, too? My thinking is that each absorption line represent one energy level of atom. It goes from lowest in infrared to highest levels in ultraviolet. If the atom is hit by an UV photon, then all the lower energy levels are for a moment not avaliable for "activation", so the corresponding lower energy/longer wavelenght absorption lines disappear too. Or is this wrong?
