Origin of continuous spectrum

In physics, a continuous spectrum usually means a set of attainable values for some physical quantity (such as energy or wavelength) that is best described as an interval of real numbers, as opposed to a discrete spectrum, a set of attainable values that is discrete in the mathematical sense, where there is a positive gap between each value and the next one. WitrynaIn 1934 the first acceptable theory for the continuous spectrum was presented. It was based on the neutrino hypothesis and was quite satisfactorily able to account for the relation between the decay rate and maximum energy of the β -particles. Furthermore, the shape of the spectrum was calculated.

WitrynaA spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules.These "fingerprints" can be compared to the previously collected ones … Witryna22 mar 2024 · Continuous spectra can be used to identify an atom.

Witryna6 sty 2024 · This is in stark contrast to the spectrum of energies that can be carried by continuous X-rays. Characteristic X-rays are created when an electron is removed from an inner electron shell, but not ... Witrynawavelengths, superimposed on the continuous spectrum. Since they are so narrow and since their wavelengths are characteristic of the target metal used, they are called characteristic lines. These lines fall into several sets, referred to as K, L,M, etc., in the order of increasing wavelength, all the lines together forming the characteristic Witryna26 lis 2024 · The term "continuous spectrum" is confusing unless you know this origin of the term, where you have a continuum of approximate eigenvalues in the limit of the discrete. Multiplication by x on L 2 [ a, b] has continuous spectrum only, and every s ∈ [ a, b] is in the continuous spectrum. several 7

Joseph von Fraunhofer (1787–1826) saw more dark lines but did not guess or deduce their origin. The currently accepted explanation – the absorption of continuous white light by vapours in the atmosphere of the Sun – was given by Gustav Kirchhoff and Robert Bunsen in the University of Heidelberg
