What is emission line spectrum?

i will solve this
Explanation:
A spectral line is a dark or bright line in a uniform and continuous spectrum, the result of an excess or a lack of photons in a narrow range of frequencies, compared to the near frequencies. When there is an excess of photons there is talk of an emission line
It is the 'decomposition' of light in a prism. Lines conform the spectrum.
Explanation:
There are emission and absorption lines
The emission spectrum of a chemical element or compound is the 'range' of frequencies of electromagnetic radiation (emitted by an atom or molecule passing from a high energy state (excited state) to a lower one or configuration with less energy).
An emission line appears in a spectrum if the source emits specific radioactive wavelengths.
A useful formula: The energy of the photon emitted is equal to the energy difference between the states.
