Absorption Spectrum: An absorption spectrum is produced when an object absorbs specific wavelengths of light from a continuous spectrum, resulting in dark lines at those wavelengths.
Emission Spectrum: An emission spectrum is produced when an object emits specific wavelengths of light, resulting in bright lines at those wavelengths against a dark background.
Continuous Spectrum: A continuous spectrum contains all possible wavelengths and shows no gaps or lines. It represents a broad range of colors without any missing parts.
