What is the emission spectrum of the sun and what does this spectrum reveal about the types of elements in the sun?
The emission spectrum of the sun is primarily a continuous spectrum with dark absorption lines, known as the Fraunhofer lines, which occur at specific wavelengths where elements in the sun's atmosphere absorb light. This spectrum reveals the presence of various elements, including hydrogen, helium, calcium, and iron, as each element absorbs light at characteristic wavelengths. By analyzing these absorption lines, scientists can determine not only the composition of the sun but also its temperature, density, and other physical properties. Overall, the sun's emission spectrum serves as a crucial tool in astrophysics for understanding stellar composition and behavior.

What does a stars dark line spectrum reveal?
A star's dark line spectrum reveals the elements present in its atmosphere. Each dark line corresponds to a specific element that has absorbed light at that particular wavelength, providing a fingerprint of the star's chemical composition. By analyzing these lines, astronomers can determine the types and abundances of elements in the star.

Examples:- chemical composition- emission spectrum- X-rays lines- melting point- color- densityand many other
Why are there empty spaces in the emission spectrum?
"Emission Spectrum" can mean a number of things... Many objects emit light and they all have an emission spectrum, that is a set of wavelengths of light that they give out. The emission spectrum for an L.E.D. bulb for instance is pretty narrow, just one visible colour. The emission spectrum of a star is very wide, encompassing non-visible light as well. It is probably these stellar emission spectra you are referring to, so I'll go on from that assumption. The fusion processes within a star (at most levels from core to surface, but mostly in the core) create most of a spectrum, but some of this light is absorbed by the outermost layers. That is why we see gaps, and molecules of certain types absorb certain parts of the spectrum, so we use the spectrum to determine composition. We also see spectra from diffuse bodies like nebulae. These are, broadly, of 2 types, emission and absorption. Absorption spectra occur when we observe a known star through the cloud, and extra lines missing beyond what we expect of the star will be emblematic of the constituents of the cloud. Emission spectra from clouds can also occur, that is when the light falling on them is not aligned with us, what we see is several narrow bands of light, which has been absorbed and re-emitted by the cloud.
What condition would cause us to see each of the three basic types of spectra?
The three basic types of spectra—continuous, absorption, and emission—are produced under different conditions. A continuous spectrum occurs when a solid, liquid, or densely packed gas is heated, emitting light across a wide range of wavelengths. An absorption spectrum appears when light from a continuous source passes through a cooler, rarer gas, which absorbs specific wavelengths, creating dark lines. An emission spectrum is generated when a gas is heated or energized, causing it to emit light at specific wavelengths characteristic of the elements present.
Will everyone see all the lines in all the emission spectra of these elements?
Many catalogues of emission spectroscopy lines are published. These lines are not visible on all types of instruments.
Which of the three types of spectrum would be observed?
The type of spectrum observed would depend on the source of light. A continuous spectrum is produced by a hot, dense object like a solid, liquid, or dense gas. An emission spectrum is generated by a thin, hot gas, while an absorption spectrum is created by a cooler gas in front of a light source.
What produces a continuous spectrum and how does it differ from other types of spectra?
A continuous spectrum is produced by a hot, dense object emitting light at all wavelengths. It differs from other types of spectra, like emission and absorption spectra, which only show specific wavelengths of light emitted or absorbed by atoms or molecules.
How do you know what elements are found in a star by studying the star?
By studying the light from the stars. This is accomplished by examining closely the 'emission spectrum' that is obtained by passing the Light gathered by the telescope through a Prism which then in turn provides the Spectrogram. Absorbtion Spectrums identify the types of substances that make up the interstellar clouds that the Light passes through!
What are the two types of spectrum?
The two types of spectrum are continuous spectrum, which shows a continuous range of colors with no gaps, and line spectrum, which consists of distinct lines of color separated by gaps.
Stars emit light types based on what?
Stars emit different types of light based on their temperature and composition. The temperature determines the peak wavelength of the light they emit, according to Wien's Law, while the elements present in a star affect the specific spectral lines observed. This emission of light spans across the electromagnetic spectrum, including visible light, ultraviolet, and infrared, reflecting both the energy processes occurring within the star and its physical characteristics.
How does the electromagnetic spectrum organize the different types of energy waves?
The electromagnetic spectrum organizes different types of electromagnetic waves according to their wavelength or frequency.
A name scientists give to the full range of types of radiation?
