When light having a continuous spectrum passes through a cool gas what kind of spectrum is produced?

When light with a continuous spectrum passes through a cool gas, it produces an absorption spectrum. In this process, specific wavelengths of light are absorbed by the gas atoms, which correspond to the energy levels of the electrons. As a result, the continuous spectrum shows dark lines, known as absorption lines, at the wavelengths where the gas has absorbed light. This phenomenon provides valuable information about the composition and properties of the gas.
