continuous spectrum Spectrum in which the radiation is distributed over all frequencies, not just a few specific frequency ranges. A prime example is the black-body radiation emitted by a hot, dense body.
Continuous Spectrum: A spectrum in which there are no absorption or emission lines.
Coronal Mass Ejection: The mass ejected from the Sun due to a solar flare.
Continuous Spectrum - A spectrum containing neither emission nor absorption lines
Convection - The process of energy transport in which heat is carried by hot, rising and cool, falling currents or bubbles of liquid or gas ...
Continuous Spectrum
(a) A spectrum composed of a continuous range of emitted or absorbed radiation. Continuous spectra are produced in the infrared and visible regions by hot solids.

CONTINUOUS SPECTRUM
A continuous spectrum is a spectrum of emitted light that contains all wavelengths of the colors that compose white light (red, orange, yellow, green, blue, indigo, violet, from long to short wavelength).
continuous spectrum - A spectrum of light comprised of radiation of a continuous range of wavelengths or colors rather than only certain discrete wavelengths.
corona - Outer atmosphere of the sun.
Continuous spectrum
Not drawn to scale.
After infra-red comes visible light. This is the range in which the sun and stars similar to it emit most of their radiation.
Continuous Spectrum: A smooth spectrum of emitted light with all wavelengths present overs some broad range of wavelengths. Blackbodies give off continuous spectra.

The continuous spectrum leads to no inference, except that of the temperature of the central globe; but the multitude of dark lines by which it is crossed reveal the elements composing pe ct rum o the truly gaseous cloaks which enclose it.
4. A continuous spectrum can be produced by a luminous solid, liquid, or _____ gas. HINT
5. An absorption spectrum is produced when a _____ gas lies in front of a source of continuous radiation. HINT ...
continuous spectrum (NASA SP-7, 1965) 1. A spectrum in which wavelengths, wave numbers, and frequencies are represented by the continuum of real numbers or a portion thereof, rather than by a discrete sequence of numbers. See discrete spectrum.
A dark line in a continuous spectrum caused by absorption of light. Each chemical element emits and absorbs radiated energy at specific wavelengths, ...
continuum The continuous spectrum that any object would produce if no absorption or emission lines were present. Any body above absolute zero emits a spectrum, the shape of which is dependant on its temperature.
Galaxies were not recognized as a distinct kind of nebular object until the late 19th century, when visual spectroscopy (Huggins) of the Andromeda spiral (M31) showed a continuous spectrum.
This analysis shows a broad and continuous spectrum of particle sizes, ranging from centimetres to several metres, with larger objects being significantly fewer in number than smaller ones.
From Leiden he continued on to Zurich, Switzerland, to work with Wolfgang Pauli on problems relating to quantum theory and the continuous spectrum, before heading back to the United States.
A hot, opaque source (black body) gives off a continuous spectrum - this is like the complete rainbow, with no gaps or breaks in it.
A heated, thin gas will produce an emission spectrum made up of discrete lines.
A hot solid, liquid or dense gas will produce a continuous spectrum (blackbody or thermal spectrum) Here, it is a hot lightbulb filament.
When William Huggins looked at the Cat's Eye, he found no continuous spectrum like that seen in the Sun, but just a few strong emission lines.
A hot solid object produces light with a continuous spectrum.
A hot tenuous gas produces light with spectral lines at discrete wavelengths (i.e. specific colors) which depend on the energy levels of the atoms in the gas.
The resultant rainbow is really a continuous spectrum that shows us the different energies of light (from red to blue) present in visible light.
The radio waves coming from double-lobed sources are undoubtedly synchrotron radiation, produced when relativistic electrons (those traveling at nearly the speed of light) emit a quasi-continuous spectrum as they gyrate wildly in magnetic fields.
A break of depression in a continuous spectrum caused by the absorption of photons within narrow wavelengths by some types of atom, ion, or molecule.
A dark-line spectrum (also called a absorption spectrum) consists of dark absorption lines superimposed on a bright continuous spectrum.
In the early 1800s, he observed that the continuous spectrum was marred by over 700 dark lines (now called Fraunhofer lines). Fraunhofer's work with the spectra and also with diffraction gratings was seminal in the science of spectroscopy.
Kirchhoff's first law: An incandescent solid or gas under high pressure will produce a continuous spectrum.
Kirchhoff's second law: A low-density gas will radiate an emission-line spectrum with an underlying emission continuum.
A spectrum of absorption lines or bands, produced when light from a hot source, itself producing a continuous spectrum, passes through a cooler gas.
Emission lines are usually seen as bright lines, or lines of increased intensity, on a continuous spectrum.

Can the plasma that fills space help spaceflight?
This is because deep sky objects comprised of stars (or objects which reflect starlight, such as reflection nebulae) shine with a continuous spectrum, ...
It was taken from an American Observatory and shows a continuous spectrum displayed over 50 strips. Within each strip the vertical black bars are absorption lines which give information about the chemical composition of the star.
Spectrum The light of an object spread out like a rainbow. As well as this continuous spectrum, a star normally shows a distinctive set of dark and light lines which are characteristic of its composition.
Emission spectroscopy uses the range of electromagnetic spectra in which a substance radiates. Hot metals, for example, radiate a continuous spectrum of many (or all) wavelengths, while excited gasses emit various discreet wavelengths, ...
astronomers using the 40 cm Foucault telescope at the Paris Observatory, discovered three stars in the constellation Cygnus (now designated HD191765, HD192103 and HD192641), that displayed broad emission bands on an otherwise continuous spectrum.
BLACKBODY - Ideal object that is a perfect absorber of light and also a perfect emitter of light. A perfect black body will absorb all radiation that falls on it, and will emit radiation that has a continuous spectrum determined only by the ...

at a total solar eclipse), that portion which is caused by sunlight scattered by protons and free electrons in the hot outer atmosphere of the Sun. The K corona extends out to about 700,000 km from the photosphere. The K Corona's continuous spectrum ...
beginning, "Dear radioactive ladies and gentlemen", he proposed the existence of a hitherto unobserved neutral particle with a small mass, no greater than 1% the mass of a proton, in order to explain the continuous spectrum of beta decay.
