It requires a certain amount of energy to raise an electron from a specific level to another specific level; the same amount of energy is released again if it falls back down. One - the electron moving up an energy level - corresponds to the absorption of energy; the other - the electron falling down - corresponds to the emission of energy.
Each chemical element has a specific emission or absorption spectrum.
The absorption spectrum and the emission spectrum of the same substance are essentially complementary because they both arise from the same electronic transitions between energy levels of atoms or molecules. When a substance absorbs light, it takes in specific wavelengths corresponding to the energy differences between these levels, creating an absorption spectrum. Conversely, when the substance emits light, it releases energy as electrons return to lower energy states, producing an emission spectrum that features the same wavelengths as those absorbed. Thus, the lines in both spectra correspond to the same energy transitions, making them identical in appearance but reversed in process.
The absorption spectrum of an element have lines in the same places as in its emission spectrum because each line in the emission spectrum corresponds to a specific transition of electrons between energy levels. When light is absorbed by the element, electrons move from lower energy levels to higher ones, creating the same lines in the absorption spectrum as the emission spectrum. The frequencies of light absorbed and emitted are the same for a specific element, resulting in matching lines.
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.

Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.

By looking at its emission spectrum and seing where the black lines are
This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.
No. The emission and absorption spectrum covers everything from UHF radio to X-rays. (There are no energy level transitions that correspond to the low energy HF or VHF radio bands and below. The lowest-energy transition is the one at 1420 MHz/21 cm.)
