What does the emission spectrum of the Sun reveal about the types of elements? In the case of the Sun light is emitted at almost all energies in the visible spectrum which is why you see all of the colors in the Sun’s spectrum. … These type of spectra can be generated for many elements by vaporizing the element in a flame.
Why does the sun emit the full light spectrum?
The visible layer of the Sun produces only a continuous spectrum because that’s what dense incandescent gases do. Outside the photosphere is a thin layer, the chromosphere, which absorbs some of the light from the photosphere. But if you can isolate the light from the chromosphere, you can see it also emits light.
Which type of emission spectrum does the Sun have?
The spectrum of the Sun appears as a continuous spectrum and is frequently represented as shown below. In the case of the Sun, light is emitted at almost all energies in the visible spectrum, which is why you see all of the colors in the Sun's spectrum. Read complete answer here.
Which type of spectrum does the sun emit?
- Ultraviolet C or (UVC) range, which spans a range of 100 to 280 nm. ...

What does an emission spectrum allow one to do?
This spectrum of radiation emitted by electrons in the excited atoms or molecules is known as the emission spectrum. It can be defined as: The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state.

What is the emission spectrum of the Sun?
The sunlight that we see — aptly named visible light — falls into only a very narrow range of the spectrum, from about 400 to 750 nanometers (a nanometer is one-billionth of a meter, or about 400 millionths of an inch). The Sun also emits at longer wavelengths, in the infrared, microwave, and radio.
What does an emission spectrum reveal?
The emission spectrum can be used to determine the composition of a material, since it is different for each element of the periodic table. One example is astronomical spectroscopy: identifying the composition of stars by analysing the received light.
What does the absorption spectrum of Sun show?
The Sun produces an absorption spectrum, with dark lines across its spectrum. Chemical elements in the Sun's corona absorb specific wavelengths of light so their electrons are excited to higher energy levels.
What is an emission spectrum quizlet?
What is an emission spectrum? In a emission spectrum (which is light), the energy is emitted by the electron as it drops to a lower energy level.
Why is the atomic emission spectrum important?
The different colors of light produced by emission spectra of different elements allows them to be identified. One use of this technique is to identify the elements present in distant stars.
Which type is the Sun's visible light spectrum and why quizlet?
The Sun's spectrum is an absorption line spectrum, which is produced when continuous light from a hot source (the Sun's interior) passes through a cooler cloud of gas (the gas that makes up the Sun's visible surface). Notice that the Sun's spectrum appears brightest (or most intense) in the yellow-green region.
What elements do you detect in the Sun's spectrum?
Although elements heavier than helium are much less common than hydrogen and helium in the Sun, elements like iron, nickel, calcium, sodium, and magnesium are prominent in the solar spectrum and are important tools for astronomers studying the Sun.
What is the difference between emission spectrum and absorption spectrum?
The main difference between emission and absorption spectra is that an emission spectrum has different coloured lines in the spectrum, whereas an absorption spectrum has dark-coloured lines in the spectrum.
What produces an emission line spectrum?
An emission line will appear in a spectrum if the source emits specific wavelengths of radiation. This emission occurs when an atom, element or molecule in an excited state returns to a configuration of lower energy.
What does a line spectrum tell us about the structure of an atom?
Explanation: The presence of spectral lines is explained by quantum mechanics in terms of the energy levels of atoms, ions and molecules. ... Emission lines occur when the electrons of an excited atom, element or molecule move between energy levels, returning towards the ground state.
How do emission and absorption spectra reveal what elements are contained in a star?
Because the wavelengths at which absorption lines occur are unique for each element, astronomers can measure the position of the lines to determine which elements are present in a target. The amount of light that is absorbed can also provide information about how much of each element is present.
