How The shortest wavelength X-rays are produced in X ray tubes
The shortest wavelength X-rays are typically produced in X-ray tubes by using a high-energy electron beam to bombard a metal target. The wavelength of the X-rays emitted in such a process is determined by the energy of the incident electrons and the atomic structure of the target material. To generate X-rays with the shortest wavelength (highest energy), you would typically need to:
-
Use a high-energy electron beam: Higher-energy electrons result in higher-energy X-rays with shorter wavelengths. This can be achieved by increasing the voltage applied to accelerate the electrons.
-
Use a target material with a high atomic number (Z): X-rays generated by bombarding a high-Z material with high-energy electrons have shorter wavelengths. Tungsten (Z = 74) is commonly used as a target material in medical X-ray machines because it produces high-energy X-rays.
-
Apply a high voltage: To accelerate the electrons to high energies, a high voltage is applied to the X-ray tube. The higher the voltage, the more energy the electrons have, resulting in shorter-wavelength X-rays.
Shortest Wavelength can be calculated by the formula - shortest Wavelength (in nanometer) = 1240 / V (in million volt)
