The intensity of X-rays from a coolidge tube is plotted against wavelength λ as shown in the figure. The minimum wavelength found is λc and the wavelength of the Kα line is λk. As the accelerating voltage is increased Beta rays emitted by a radioactive material are.

The minimum wavelength found is λc and the wavelength of the Kα line is λk. As the accelerating voltage is increasedElectrons with de- Broglie wavelength λ fall on the target in an X- rays tube . The cut off wavelength of the emitted X- rays isElectrons with de-Broglie wavelength λ fall on the target in an X−ray tube. The cut-off wavelength of the emitted X−rays is
