An incandescent light (glowing tungsten filament)produces:
A)a continuous spectrum, with the peak giving the temperature of the filament.
B)an emission spectrum, with bright lines due to ionized tungsten.
C)an absorption spectrum, with dark lines due to the solid filament.
D)a continuum, with bright tungsten lines added.
E)a continuum, with dark lines of tungsten and argon as well.

Question

Quizplus · Accepted Answer

An incandescent light bulb produces a continuous spectrum of light, meaning that it emits light at all wavelengths across the visible spectrum. The peak of the spectrum corresponds to the temperature of the tungsten filament, which glows white-hot when an electric current is passed through it. There are no bright or dark lines in the spectrum, as in emission or absorption spectra. An incandescent light produces a continuous spectrum, which is a rainbow of colors with no breaks or gaps, indicating that all wavelengths are being emitted. The peak wavelength of the spectrum gives the temperature of the filament.
