See more at spectrum Examples of emission spectrumemission spectrum The lower section shows that the emissionspectrum of the donor dye must (partially) overlap with the absorption spectrum of the acceptor dye. The resulting spectrum is able to match the emissionspectrum of a protoplanetary nebula. Thus, there exists a good match between the flashboard emissionspectrum and the absorption proper ties of argon. The emissionspectrum is much broader in the present case than in the low light intensities. Emitted light from this plasma amounts to an elemental emissionspectrum that is collected and used to identify the composition of the target material1. The emissionspectrum characteristics of some elements are plainly visible to the naked eye when these elements are heated.

Due to its high sensitivity to the mobility and presence of solvent dipoles, changes in the emissionspectrum can be calculated from the generalized polarization.

The collection would be equivalent to an array of semiconductors individually size tuned for optimal absorption at their bandgaps throughout the solar energy emissionspectrum.

It glows blue with an emissionspectrum peak wavelength at 430 nm, which makes it useful as a wavelength shifter.

The principle of the atomic emissionspectrum explains the varied colors in neon signs, as well as chemical flame test results (described below).

Starlight can be understood to be composed of three main spectra types, "continuous spectrum", "emissionspectrum", and "absorption spectrum".

This collection of different transitions, leading to different radiated wavelengths, make up an emissionspectrum.

The fact that only certain colors appear in an element's atomic emissionspectrum means that only certain frequencies of light are emitted.
