Spectral line absorption profile

A 2D wavelength plot showing a single absorption line as a narrow symmetric downward trough cut into a bright horizontal continuum line. The continuum remains flat on both sides, while the line dips smoothly to a minimum at the center, forming a centered spectral-line profile, in a clean scientific plot style with a thin black or dark blue curve on a white background.
