Does the Sun produce a continuous spectrum or an absorption spectrum?

The photosphere of the sun doesn't really produce a continuous spectrum; there are discontinuities corresponding to energy levels of various chemical elements, called spectral lines. Notably Helium was discovered in the absorption lines of the solar spectrum and only later discovered on Earth.

Why is the solar spectrum an absorption spectrum rather than an emission spectrum?
The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
What conditions produce a dark-line spectrum?
An absorption spectrum can tell the astronomer or physicist what elements are in the starlight being observed. A diffraction grating is used to split the incoming light into a spectrum of colors. Sodium, for example, causes dark Fraunhofer lines at known points in the visible spectrum. Helium was discovered in the solar spectrum by Bunsen and Kirchoff using this technique. Hence the name derived from Helios for the Sun.
What is non-luminance?
The non-luminous is those objects which do not produce its own light.It provide the light which is reflecting from another e.g.moon did not produce its own light,sun is giving the light to moon,moon reflecting the light of sun.
Would a plant produce more oxygen on a cloudy day or on a sunny day?
On a sunny day because there is more sun to help produce oxygen
Why can the Sun not produce heavier elements beyond carbon and oxygen?
The sun does not have enough mass or a hot enough core to fuse heavier elements such as carbon and oxygen.
What type of spectrum do we see from the sun?
some of the light from the corona produces a continuous spectrum that lacks absorption lines. however the type is absorption spectrum
What type of spectrum does the Sun's photosphere produce?
Visible light is a portion of the electromagnetic radiation that is visible to the human eye. Stars Emit their own light. visible Light has a Wavelength of around 80 or 400 nm to about 760 or 780 nm
Does the sun give off a discontinuous spectrum?
No. The sun gives off a full continuous spectrum.
What are examples of atomic absorption spectroscopy?
When white light from mercury vapour lamp is passed through sodium vapour then we have as outcome a continuous spectrum of colours with two black lines in the yellow-orange region. These two lines stand for the absorption of 5890 A and 5896 A lines of sodium atom Another example is Fraunhofer lines seen in the continuous spectrum got from sun. These lines are due to absorption of characteristic frequencies of metals present in the chromosphere of the sun
How a star is similar to the sun if it has the same absorption lines in its spectrum that occur in the sun spectrum?
because they will have the same elements in the atmosphere...
Is the continuous spectrum really continuous Or just too close to distinguish?
The spectrum produced by something that's heated, like the sun or an incandescent light, is continuous.
What can be determined by studying a solar spectrum?
Dark lines of the absorption spectrum give the elemental composition of the chromosphere, information about the magnetic field and density of the surface. The peak of the continuous spectrum gives the surface temperature. The Doppler Effect shows the movement of the sun and the sun's surface. Splitting of spectral lines verifies the magnetism of sunspots.
What can be said about the star composition if the spectrum of a star shows the same absorption lines as the sun?
If the spectrum of a star shows the same absorption lines as the sun than you know that the star has the same composition as the sun. This means that the star is made of the same elements as the sun.
How a star is similar to the sun if it has the same absorption lines in its spectrrum that occur in the sun's spectrum?
Because the sun is a star
Why does the sun produce a continuous spectrum but the fluorescent lights produce a line spectrum?
The sun produces a (nearly) continuous spectrum (gaseous elements in the Sun's atmosphere absorb certain frequencies, making it not quite truly continuous) because it's emitting light due mainly to its temperature. This kind of radiation is called "black body" or "cavity" radiation, and it's a continuous spectrum. Fluorescent lights produce light by a phenomenon known as (hold on for the shocking revelation) fluorescence. This kind of radiation is related to transitions between specific electron energy levels, and therefore consists of discrete lines. In old or cheap fluorescent tubes, there might be only a couple of lines. Most modern ones use a mixture of phosphors that emit light at different frequencies, so you might see half a dozen or more lines in the spectrum.
Which type of spectrum do most stars have?
Most stars have absorption spectra. In other words, stars possess thin outer layers that allow light to pass through. These layers produce what are called absorption lines. This means the light from the sun and stars are absorption spectra.
How a star is similar to the sun if it has the same absorption lines in its spectrum that occur in the suns spectrum?
because they will have the same elements in the atmosphere...
