Vedclass · Answer

(D) The emission of characteristic $X$-rays starts only when the incident electrons are accelerated beyond a certain critical value. Once this threshold is exceeded,the intensity of the characteristic lines relative to the continuous (white) spectrum increases,but the wavelengths of these characteristic lines remain unchanged because they depend only on the atomic structure of the target material.

When the accelerating voltage applied to the electrons is increased beyond a critical value in an $X$-ray tube,what happens to the $X$-ray spectrum?

Electrons of mass $m$ with de-Broglie wavelength $\lambda$ fall on the target in an $X$-ray tube. The cutoff wavelength $(\lambda_0)$ of the emitted $X$-ray is

In an $X-ray$ tube,when the accelerating voltage $V$ is halved,the difference between the wavelength of the $K_{\alpha}$ line and the minimum wavelength of the continuous $X-ray$ spectrum:

Electrons with energy $80 \ keV$ are incident on the tungsten target of an $X$-ray tube. $K$-shell electrons of tungsten have an ionization energy of $72.5 \ keV$. The $X$-rays emitted by the tube contain only:

Characteristic $X$-rays:

The energy of the $L$ shell is $7200$ units and the energy of the $K$ shell is $1800$ units. Therefore,the energy of the $K_\alpha$ line is equal to ...... units.
