What is discrete X-ray spectrum?

In an X-ray tube, in addition to the continuous spectrum of radiation emitted by the decelerating electrons, there is also a spectrum of discrete X-ray emission lines that is characteristic of the target material. This energy difference usually corresponds to photon wavelengths in the X-ray region of the spectrum.

What is the spectrum of X-rays?

The x-ray spectrum is defined as the energy distribution of the radia- tion produced in an x-ray exposure. The x-ray spectrum has a major impact on image quality and radiation dose delivered to patients.

What are the two types of X-ray spectrum?

There are two main X-ray spectroscopy techniques: wavelength-dispersive X-ray spectroscopy (WDXS) and energy-dispersive X-ray spectroscopy (EDXS). WDXS measures the X-rays of a single wavelength that are diffracted by a crystal.

What type of X-rays have a continuous energy spectrum instead of a discrete spectrum )?

Bremsstrahlung
Bremsstrahlung has a continuous spectrum, which becomes more intense and whose peak intensity shifts toward higher frequencies as the change of the energy of the decelerated particles increases.

What is white radiation?

Some of the collisions between the thermionic electrons and the target result in the emission of a continuous spectrum of X rays called white radiation or Bremsstrahlung. White radiation is believed due to the collision of the accelerated electrons with the atomic nuclei of the target atoms.

What is the difference between a continuous spectrum and a discrete spectrum?

Typically one can observe two distinctive classes of spectra: continous and discrete. For a continuous spectrum, the light is composed of a wide, continuous range of colors (energies). With discrete spectra, one sees only bright or dark lines at very distinct and sharply-defined colors (energies).

Why is copper K alpha?

K(alpha) is more intense than k(beta). Copper targets are easier to cool than most other possible electrodes. Most references have standardized on the Cu k(alpa) so it is easier refer to other results. Other wavelengths are acceptable.

What are quantized properties?

A quantized property is one which comes in a definite size and the property may be obtained in a multiple of that definite size.

What causes a discrete spectrum?

In classical mechanics, discrete spectra are often associated to waves and oscillations in a bounded object or domain. Discrete spectra are also produced by some non-linear oscillators where the relevant quantity has a non-sinusoidal waveform.

Why do we get discrete spectrum instead of a continuous spectrum in hydrogen spectrum?

Atoms of individual elements emit light at only specific wavelengths, producing a line spectrum rather than the continuous spectrum of all wavelengths produced by a hot object.
