Which of the following statements is(are) true about absorption or emission? Select all the correct answer(s). When atoms absorb light, the electrons go from a high energy level to a low energy level. A spectroscope is used to study the emission spectra of substances. As electron transitions from an excited state to a lower energy state, light is emitted with an energy equal to the difference in the two states. Emission spectrum is like a "finger print" of a substance which can be used for identification.
