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.
A dark-line spectrum, also known as an absorption spectrum, is produced when light passes through a cooler, low-density gas or plasma and is absorbed by specific elements or molecules. The dark lines in the spectrum correspond to the wavelengths of light that have been absorbed by the gas, indicating the presence of specific elements or molecules in the gas.
The 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.
The colors on the color spectrum combined to produce gray are black and white.
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.
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.
Magnesium does not produce a color in the flame test because it emits ultraviolet light that is not visible to the human eye. The energy emitted by magnesium when heated is at a wavelength that is outside the visible spectrum, so it does not result in a characteristic color.
An absorption spectrum shows the wavelengths of light absorbed by a substance, appearing as dark lines on a bright background. An emission spectrum shows the wavelengths of light emitted by a substance, appearing as bright lines on a dark background. In other words, absorption involves light being absorbed by the substance, while emission involves light being emitted by the substance.
The colors on the color spectrum combined to produce gray are black and white.
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.
A diffraction grating does.
Rain droplets can refract light. Different colours refract in different amounts so a spectrum is produced.
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.
Well I know if you heat a rock until it glows, its spectrum will be thermal radaition spectrum

The color produced when burning an element is due to the emission of light by the excited electrons in the atoms of that element. The energy absorbed during heating causes the electrons to jump to higher energy levels, and when they return to their original levels, they release this energy in the form of light, leading to the observed color.
