it refers to the gas that are emitted from the ehaust of the car. it is caused by the combustion of gas inside the engine.
Red, blue, green, and violet are found in the emission spectrum of hydrogen.
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
No.
No. Atomic emission spectrum is non-contiuous and it is named as line spectrum.
To identify an unknown sample by its emission spectrum
absorption spectrum
No. It is not possible for two metals to have the same emission spectrum. For metals to have the same emission spectrum, they would need for their electrons to have duplicate orbitals. That would be impossible due to the exclusion principle.
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
Identify elements
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.
Red, blue, green, and violet are found in the emission spectrum of hydrogen.
because the emission wavelengths of mercury are very precisely known.
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.
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
The emission spectrum can be used to determine the composition of a material
