Question

What characteristic of the electron striking the target in a Coolidge tube that determines the upper limit of frequency of continuous $X-rays$ that can be analysed with it ?

• A. Energy
• B. Momentum
• C. Number incident per second
• D. Mass

Answer 1

Answer: (A)

Energy

The frequency of $X$-rays generated is given by the $h{\nu }_{max}=eV$, where $eV$ is the kinetic energy carried by the striking electron.
