What is the difference between a emission nebula and a reflection nebula?

Emission nebula glow and reflection nebula reflect the light form other stars


How are absorption and emission lines produced in a stellar spectrum What information might absorption lines in the spectrum of a star reveal about a cloud of cool gas lying between us and the star?

Absorption lines are produced when elements in the outer layers of a star absorb specific wavelengths of light, leading to dark lines in the spectrum. These lines indicate the presence of certain chemical elements in the star's atmosphere. Absorption lines from a cool gas cloud between a star and Earth can reveal the composition, density, and temperature of the cloud, providing valuable information about the interstellar medium.


Layer of the sun between core and convection zone?

The layer of the sun between the core and the convection zone is the radiative zone. In the radiative zone, energy moves outward primarily through the absorption and re-emission of photons by ionized atoms. This process takes place over millions of years as the energy slowly diffuses through this layer before reaching the convective zone.


What is the meaning of radiation zone?

The radiation zone is a region in the interior of a star where energy is transported outward by electromagnetic radiation, primarily in the form of photons. In this zone, energy is carried through the star's layers by the absorption and re-emission of photons. The radiation zone is located between the core and the convection zone of a star.


If a star is moving away from you the absorption lines in its spectrum will?

be shifted towards the red end of the spectrum due to the Doppler effect, known as redshift. This occurs because the wavelengths of light are stretched as the star moves away from the observer, causing the absorption lines to shift to longer wavelengths.

What are the similarities between emission and absorption spectra?

The lines are at the same frequencies


What is the difference between an absorption and an emission spectrum?

Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.


What is the difference between absorption and emission spectrum?

Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.


How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?

The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.


What is the simailarity and difference of flame emission and atomic absorption spectroscopy?

Both flame emission and atomic absorption spectroscopy are analytical techniques used to determine the concentration of elements in a sample. The main similarity is that they both rely on the excitation of atoms in the sample to emit or absorb specific wavelengths of light. The main difference is that in flame emission spectroscopy, the intensity of emitted light is measured, while in atomic absorption spectroscopy, the amount of light absorbed by the atoms is measured.


How do emission and absorption spectrums tell us about the composition of objects in our universe?

Each chemical element has a specific emission or absorption spectrum.


When is atomic absorption more sensitive than atomic emission in atomic absorption spectrometers?

Atomic absorption is more sensitive to atomic emission when the excitation potential is greater than 3.5eV.


What are t he difference between reflection and emission?

reflecttion is a part of incidentradiant but emission may be different of incident radiant.


What are the strenghts of atomic absorption spectrometry compared to atomic emission spectrometry?

Atomic absorption spectrometry is more sensitive than atomic emission spectrometry.


What is the difference between emission and absorption in terms of what happens to an electron in an atom?

During emission, an electron in an atom transitions from a higher energy level to a lower energy level, releasing a photon in the process. In absorption, an electron absorbs a photon and transitions from a lower energy level to a higher energy level within the atom.


What is the difference between field emission and photoelectric emission?

* emisssion of electron from the surface of the metal when light of suitable frequency falls-photoelectric emission. * emision of electron from the metal by quantum tunnling of electron.


What is the difference between raman effect and flueroscence?

The Raman effect is the inelastic scattering of light by molecules, resulting in a shift in wavelength. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Both phenomena involve interactions between light and molecules but differ in the mechanism of light emission.
