CHARACTERISTIC X-RAY SPECTRA
Superimposed on the continuous X-ray spectrum described above are sharp intensity peaks occurring at wavelengths which depend on the target material and not on the p.d. across the tube. For most elements commonly used as targets these intensity peaks occur in two groups, one at lower wavelengths called the K-series and a longer wavelength group called the L-series. For elements with atomic number greater than 66 even longer wavelength series, the M- and N-series occur.
In 1913 Moseley investigated these characteristic spectra and discovered a linear relationship between the square root of the wave numbers for the lines of the K-series for various elements and the atomic numbers of the elements. Figure 27.5 shows a plot of against Z for the longest wavelength member of the K-series (the Kα-line) for a number of elements against the atomic number Z of the element, R being the Rydberg constant. The straight line fits the equation , which may be written as.
Explanation:
Answer:
It consists of radiations of all the possible wavelength from a certain lower limit to higher values continuously , as in case of visible light .
