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.

∙ 12y agoThe conditions that produce a dark line spectrum are: a source of wideband energy behind an atom. The energy washes over the atom and the atom absorbs energy associated with electron level resonance. This absorption by the atom creates the dark lines in the spectrum because the energy at these lines has been absorbed by the atoms electrons absrbing the energy and jumping to higher atomic levels.

What colors on the color spectrum combine to produce gray?
The colors on the color spectrum combined to produce gray are black and white.
Which type of spectrum can be produced by solid liquid or gas?
The spectrum produced by solid is continuous spectrum. Continuous spectrum is formed by all, solid liquid and gases if the pressure is high. In case of low pressure, gases produce line spectrum.
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.
What causes the color when you burn an element?
A spectrum is what it is called when an element burns and produce light. The spectrum of an element is based on what orbit the electrons are in and what energy level the electrons are at.
What kind of conditions can produce hydrolysis of an ester?
basic

What simple device uses diffraction to produce a better spectrum than a prism can produce?
A diffraction grating does.
How do raindrops produce a spectrum?
Rain droplets can refract light. Different colours refract in different amounts so a spectrum is produced.
What element can produce an atomic emission spectrum in its natural state neon chlorine silicon or Krypton?
Every element can produce an emission spectrum, if it is sufficiently heated. Of the 4 elements that you mention, neon is the most useful, in terms of its emission spectrum, and it is used in a certain type of lighting.
If you heat a piece of wire until it glow's what type of spectrum does it produce?
Well I know if you heat a rock until it glows, its spectrum will be thermal radaition spectrum
What is the light produce a spectrum as it passes through the prism what is the process called?
Refraction
What is the name of the spectrum when elements produce different colors when heated?
Atomic spectra

What is a piece of glass with many small parallel lines etched on its surface to produce a spectrum?
Grating.
What is the reasons why to produce guns?
Market conditions.
