Consider a continuous X-ray photon emitted from a Coolidge tube. The energy of this photon is derived from
Options
- Athe kinetic energy of the free electrons in the target
- Bthe kinetic energy of the striking electron
- Can atomic transition within the target
- Dthe kinetic energy of the ions in the target
Correct answer
B. the kinetic energy of the striking electron
Step-by-step solution
Continuous X-rays are produced due to the deceleration of high-speed electrons when they strike the target material in a Coolidge tube.
The loss in the kinetic energy of these striking electrons is emitted as continuous X-ray photons, also known as Bremsstrahlung radiation.
Characteristic X-rays, on the other hand, are produced due to atomic transitions within the target atoms.
Thus, the energy of a continuous X-ray photon is derived from the kinetic energy of the striking electron.
