What are the lines on an absorption spectrum?
Absorption lines are usually seen as dark lines, or lines of reduced intensity, on a continuous spectrum. This is seen in the spectra of stars, where gas (mostly hydrogen) in the outer layers of the star absorbs some of the light from the underlying thermal blackbody spectrum.
How many lines will be possible in the absorption spectrum when a hydrogen atom in the ground state is excited by radiations of wavelength 975 á?
∴ Number of lines possible in the resultant spectrum = 6, as shown in Fig below.
How many lines can you see in the sun’s actual spectrum?
The spectrum is so long and detailed that it had to be cut into strips; each of the 50 strips spans a wavelength range of 6 nanometers (60 angstroms). The dark lines throughout the spectrum are caused by absorption of light by various elements in the Sun’s atmosphere.
How many emission lines are possible?
One emission line will be produced resulting from the energy change in which an n = 6 to n = 2 transition occurs, as well as from every other distinct energy change. The maximum possible omission lines is 10.
How are absorption lines formed?
An absorption line occurs when an electron jumps from a lower energy state to a higher energy state, extracting the required photon from an outside source of energy such as the continuous spectrum of a hot, glowing object.
How many line spectra is possibly occurred when the hydrogen atom is transitioned back to a ground state?
These are the spectral lines which shall occur when electron jumps from 6th orbit to the ground state. As you can see we have 15 spectral lines. So if an electron jumps from nth orbit to ground state, total n(n-1)/2 no. of spectral lines are formed.
When a hydrogen atom is raised from the ground state?
Hence, when a hydrogen atom is raised from ground state to excited state, its potential energy increases whereas kinetic energy decreases.
Is absorption spectrum continuous?
The absorption spectra are obtained when atoms absorb energy. It is a discontinuous spectrum consisting of a few wavelengths with distinct spacing between them. It is a continuous spectrum, consisting of all the wavelengths having dark lines between them.
How does an absorption spectrum differ in appearance from an emission spectrum?
how does an absorption spectrum differ in appearance from an emission spectrum? an emission spectrum consists of bright lines against a dark background, whereas an absorption spectrum consists of dark line against a bright rainbow background.
