The Sun emits a continuous spectrum, but some elements in its atmosphere absorb some of the light. Hydrogen atoms, for example, absorb light emitted by other masses of heated hydrogen.

spectrum (pl spectra): The result of spreading a beam of electromagnetic radiation so that components with different wavelengths are separated. wavelength: The distance between one peak or crest ...

IN spectroscopic literature there are many casual references to a continuous background in the vacuum tube spectra of various gases, such as oxygen, chlorine, etc. Usually these observations ...

IN recent papers I have discussed the continuous spectrum of mercury and its association with the resonance line λ2537. Prof. R. W. Wood showed in 1909 that the green visual fluorescence of ...

IMM Photonics presents a newly developed LED featuring a continuous spectrum from 400 nm to 750 nm. Due to their internal design, standard white LEDs have a gap in the spectrum between 400 nm and 450 ...

Spectra Absorption spectra All elements either emit or absorb certain frequencies of light. Evidence from atomic line spectra supports the Bohr model of the atom using photon frequency calculations.
