    What is the difference between emission and absorption spectra?
    The main difference between emission and absorption spectra is that an emission spectrum has different coloured lines in the spectrum, whereas an absorption spectrum has dark-coloured lines in the spectrum. More differences between absorption and emission spectrum are given below in a tabular column.

    What is the difference between atomic emission and atomic absorption spectroscopy?
    \ [ E=mc^2 \label {eq:mc2} \] Both atomic emission and atomic absorption spectroscopy can be used to analyze samples. Atomic emission spectroscopy measures the intensity of light emitted by the excited atoms, while atomic absorption spectroscopy measures the light absorbed by atomic absorption.

    What is an absorption spectrum?
    An absorption spectrum is constituted by the frequencies of light transmitted with dark bands when energy is absorbed by the electrons in the ground state to reach higher energy states. How does electromagnetic radiation occur?

    What are the wavelengths of the absorption spectrum?
    The wavelengths of the black lines in the bar of the “Absorption Spectrum” correspond to the wavelengths of colored lines in the bar of the “Emission Spectrum.” The wavelengths of the valleys in the graph of the “Absorption Spectrum” correspond to the wavelengths of colored lines in the peaks of the “Emission Spectrum” graph.

    How is the emission spectrum formed?
    The emission spectrum is formed by the frequencies of this emitted light. What is the Absorption Spectrum? On the other hand, an absorption spectrum is constituted by the frequencies of light transmitted with dark bands when energy is absorbed by the electrons in the ground state to reach higher energy states.

    What do the black lines on absorption spectra mean?
    Instead of showing the photons being emitted by the electrons of a gas, it shows where they are being absorbed. The black lines on the absorption spectra indicate regions where there is no light of that specific wavelength. Absorption spectra are produced when light passes through a gas on its way through a prism, like in the figure below.
