spectrum of electromagnetic radiation emitted by a self-luminous source
the collection of discrete wavelengths emitted by atoms that have been excited by heating or by electric currents
the spectrum of radiation intensity vs. wavelength or frequency produced when atoms, ions or molecules relax from high energy states to lower energy states.
a series of unevenly spaced lines of different colors and brightness
Bands of light emitted by rarefied gas at specific wavelengths. A gas's emission spectrum is unique and, therefore, can be used to identify that gas.
The pattern of spectral emission lines, produced by an element. Each element has its own unique emission spectrum.
A spectrum consisting of emission lines.
An emission spectrum (also called a bright-line spectrum) is a discontinuous spectrum (discrete bright bands) that is emitted by atoms or molecules. The emission spectrum is characteristic of the chemicals which are emitting the photons. It looks like a series of bright lines on a black background (this is called spectroscopy).
A spectrum containing emission lines
Spectrum associated with emission of electromagnetic radiation by atoms (or other species) resulting from electronic transitions from higher to lower energy states.
Spectrum containing bright lines or a set of discrete wavelengths produced in a rarefied incandescent gas.
The detailed dependence on wavelength of the intensity of radiation emitted by a given radiator. Emission spectra are typically composed of discrete spectral lines and bands of overlapping lines, which depend on the molecular or atomic composition of the emitting substance and which may be used to identify it uniquely.
The spectrum produced when atoms are excited and give off energy.
An element's emission spectrum is the relative intensity of electromagnetic radiation of each frequency it emits when it is heated (or more generally when it is excited).
