Absorption spectrum Explanation

Absorption spectrum is the spectrum of electromagnetic radiation transmitted through a substance, showing dark lines or bands due to absorption at specific wavelengths. Absorption spectra are what you get when you shine white light through a gas. Certain colors (energies) of light are absorbed by the gas, causing black bars (gaps) to appear in the spectrum.
