Explain the production of X-rays by Coolidge tube with the help of a diagram. How are the intensity and the penetrating power of the X-rays controlled in this?

What do you mean by minimum wavelength limit of X-rays? If a Coolidge X-ray tube is operated at $V$ volt then prove that the shortest wavelength of the X-rays emitted will be given by

${\lambda }_{min}=\frac{1.2375\times {10}^{-6}}{V}\mathrm{m}$.
