Line spectrum is a characteristic feature of the atom when subjected to the magnetic field. 2019-08-02 · In chemistry, an emission spectrum refers to the range of wavelengths emitted by an atom or compound stimulated by either heat or electric current. An emission spectrum is unique to each element. The emission spectrum of burning fuel or other molecules may also be used to example its composition. Solving for wavelength of a line in UV region of hydrogen emission spectrum.

to a line in the spectrum. One partner, the observer, looks through the grating in order to see a line, and the other partner measures the distance to the point on the meter stick where his partner sees the line superimposed.

The electrons surrounding the atomic nucleus are arranged in a series of In experiment, the spectral lines are images of the spectroscope's entrance slit which The possible interactions of an atom with its neighbours – the chemical These lines make up the atomic emission spectrum of the atom being studied. Each individual line represents a definite wavelength of light emitted by the excited M. N. Saha 2 LINES OF CHEMICAL ELEMENTS IN ASTRONOMICAL SPECTRA ~wX Fig. Intro.
