What is the emission spectrum for sodium?

What is the emission spectrum for sodium?

The sodium spectrum is dominated by the bright doublet known as the Sodium D- lines at 588.9950 and 589.5924 nanometers. From the energy level diagram it can be seen that these lines are emitted in a transition from the 3p to the 3s levels.

What is atomic spectra explain absorption and emission spectrum?

The emission spectra are obtained due to radiations emitted by excited atoms. The absorption spectra are obtained when atoms absorb energy. An atom will be having higher energy while exhibiting an emission spectrum. An atom will be having lower energy while exhibiting an emission spectrum.

How do you describe the atomic emission spectrum?

An atomic emission spectrum is the pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains. Each of these spectral lines corresponds to a different electron transition from a higher energy state to a lower energy state.

How does the atomic emission spectrum of sodium on earth compare to the atomic emission spectrum of sodium in the sun?

Option a (the same) is the correct answer. The emission spectra is a result of electrons transitioning from higher energy levels to lower energy levels. As a result, a sodium atom on Earth will have the same emission spectrum as a sodium atom in the sun.

What is an absorption spectrum definition?

Definition of absorption spectrum : an electromagnetic spectrum in which a decrease in intensity of radiation at specific wavelengths or ranges of wavelengths characteristic of an absorbing substance is manifested especially as a pattern of dark lines or bands.

Why does the atomic emission spectrum of sodium consist of one yellow line?

Unlike blackbody radiation, the color of the light emitted by the hydrogen atoms does not depend greatly on the temperature of the gas in the tube. With sodium, however, we observe a yellow color because the most intense lines in its spectrum are in the yellow portion of the spectrum, at about 589 nm.

What is meant by emission spectrum Ncert?

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 emission spectrum in 10th class?

An emission spectrum is the range or array of wavelengths (spectra) obtained when the light emitted by a substance is passed through a prism and examined directly with a spectroscope.

How is an absorption spectrum created?

An absorption spectrum occurs when light passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies; since the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives rise to dark lines (absence of light) in the spectrum.

How do the energy differences between the higher energy levels of an atom compared with the energy difference between the lower energy levels of the atom?

How do the energy differences between the higher energy levels of an atom compare with the energy differences between the lower energy levels of the atom? They are smaller in magnitude than those between lower energy levels. What are quanta of light called?

What is the kind of atomic spectrum?

There are three types of atomic spectra and they are emission spectra, absorption spectra, and continuous spectra.
