Continuous Spectrum

(smooth spectrum or portion of spectrum with no lines)

The term Continuous Spectrum (or Continuum) refers to a spectrum or portion of a spectrum that is smooth, i.e., with no Spectral Lines. Black-Body Radiation has such a continuous spectrum. The term is also used to refer to the spectrum on either side of a specific spectral line, or what the spectrum would be without that line, e.g., in describing the line's depth or shape.

The term Discrete Spectrum refers to an unsmooth spectrum, e.g., with lines.
