What else can I help you with?
If a star's spectrum does not contain spectral lines characteristic of a certain element can we conclude that the star do not contain that element Why or Why not?
Not necessarily. The absence of specific spectral lines could be due to factors like the star's temperature, composition, or magnetic fields affecting the spectral lines. It could also be that the element is present in trace amounts that are not detectable in the spectrum.
What would red shift do to helium's Fraunhofer lines?
Red shift would cause helium's Fraunhofer lines to shift towards the red end of the spectrum. This occurs because as the light from the helium source is redshifted, the wavelengths of the spectral lines observed would also increase, causing them to appear at longer wavelengths.
Why is the part of the electromagnetic spectrum you can see called ultraviolet light?
Its not. You can't see ultraviolet. (it lies just above the visible spectrum.)
The part of the spectrum that can be separated into rainbow-like colors is?
The visible light spectrum is the part of the spectrum that can be separated into rainbow-like colors. This range of wavelengths extends from about 400 nanometers (violet) to 700 nanometers (red).
How an absorption spectrum can identify a star's composition?
By looking at the lines in a star's spectrum of light, astronomers can tell what kinds of elements the star is made of. This happens because when a beam of light hits an atom or molecule, that atom absorbs a characteristic wavelength (color) of visible light. Scientists have made a huge list of different elements and the different patterns of lines observed in theirj corresponding "spectra" (fancy word for light spectrums), and by using such lists can deduce precisely what each star is made of.
Do dark dust clouds radiate mainly in the ultraviolet part of the electromagnetic spectrum?
Dark dust clouds primarily absorb and scatter visible light, hence appearing dark to us. They do not radiate strongly in the ultraviolet part of the electromagnetic spectrum.
What is the part of the em spectrum that we can see?
The part of the electromagnetic spectrum that we can see is visible light. Visible light consists of the colors of the rainbow, ranging from violet at shorter wavelengths to red at longer wavelengths. This portion of the spectrum is detected by our eyes and is responsible for our sense of sight.
What is the emission spectrum of barium nitrate?
The emission spectrum of barium nitrate typically includes several bands of light in the visible region, with some lines in the blue-green part of the spectrum being the most prominent. The specific wavelengths and intensities of these lines can vary depending on the experimental conditions.
What is a spectroscopy?
It is putting the light from the Sun or a star through a spectrograph, in other words a specially designed piece of equipment with a prism, to split it up into its different colours, red to violet. A spectrosope uses collimated light so that each 'colour' or wavelength arrives in its own measureable position on the spectrum. When that is done, a set of dark lines can be seen in the spectrum, each line corresponding to an element or compound in the source that provided the light. The sodium lines in the yellow part of the spectrum are a good example, and in the Sun's spectrum there are two dark lines close together in the yellow region, indicating that sodium is absorbing light in the outer layers of the Sun. This technique is used to analyse stars in great detail to discover their chemical makeup.

What part of chloroplast is responsible for dar reaction?
Stroma is the site for dark reaction.It does not light.
Waves given off by electric power lines are too to be seen?
The electromagnetic waves given off by high voltage power lines are beyond the visible part of the spectrum.
What is Radiant light energy?
Radiant light energy refers to the energy carried by electromagnetic waves that are visible to the human eye. This energy is part of the electromagnetic spectrum and is responsible for the sensation of sight. It includes all the colors of light that we can perceive.
What part of the electromagnetic spectrum do you feel as heat from the sun?
Heat from the sun is primarily felt as infrared radiation, which falls within the electromagnetic spectrum just below visible light. Infrared radiation is responsible for warming our skin and the Earth's surface.
Why line spectrum is called finger print spectrum?
It is unique to a specific atom. The emission spectrum of sodium, for example, has two characteristic lines close together in the yellow part of the spectrum, which cannot be found in any other atom. Each line in a spectrum relates to a change in electron state or level.
What is the part of the electromagnetic spectrum called?
We call that the visible or optical spectrum.
What part of the spectrum could i detect with your sense of sight?
The visible spectrum
