When the electron changes levels, it decreases energy and the atom emits electromagnetic radiation in the form of 'photons'. Both energy absorption and emission events release particles. When an atom absorbs energy, its electron quasi particles move to a higher energy level and it re-emits it in a random direction. The photon-like particle is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
As every reaction has equal and opposite reaction,absorption and emission spectra are associated with wavelength of quanta released ?
Dear Kolemann
Since typical daylight involves the whole spectrum, absorption spectra is related to light filtering through a given substance that absorbs most of the frequencies that resonate with the energy levels of the electrons stabilized in their rest states in this type of atoms.
Emission spectra on the other hand are frequencies emitted by a substance when you energize it by shooting energy at it. Its electrons become overexcited, jump to further away metastable orbitals and immediately jump back to their rest orbitals, releasing a photon of the frequency detected.
In electromagnetic mechanics, photon emission and absorption is analyzed in Section 28 and 29 of this article:

Dear Kolemann Lutz our science is practicing standard modeling of atom with electron, but up to this date electron never been observed.
Unfortunately our science is totally wrong with perception of light (without photon) and sunlight (with photon) , which these two are totally different from each other.
Article Title: Science is wrong on…Light & Photon
I suggest that you read the paper I just uploaded in the discussion part. It will give you a better idea of, what is an atom.
