Unformatted text preview: --------An electron can jump up from a lower to higher energy levels-But, it needs energy to do this.-A photon of light can provide the energy.-However, not every photon can do the trick.-If the photons energy matches the energy difference Between the levels, the photon will be absorbed,-Otherwise it will fly away (Electrons absorbs a photon, causing it to jump to a higher energy level) Because electrons exist only at specific energy levels, photons are emitted & absorbed with specific energies. Absorption Spectrum Emission Spectrum Photons of different wavelengths have different energy. So atoms absorb or emit only certain wavelengths (or colors) of light...
