the variation with wavelength of the intensity of the X-ray beam for different X-ray tube voltages of V, and V2. Tube voltage Intensity V2 (> V1) Intensity Tube peaks voltage V1 Amin Amin Wavelength for V2 for V1 Fig. 8.1 (a) For the intensity due to the higher tube voltage, explain why (i) its minimum wavelength is lower, (ii) the series of peaks superimposed on the continuous distribution of wavelengths is at the same wavelengths regardless of the tube voltage. (b) Suggest why the intensity of the continuous distribution of wavelengths is higher for the higher tube voltage
