4:50 PM Thu 28 Apr < то (b) The diagram below shows an x-ray tube schematic. Vacuum Filament Electrons Tungsten target X-Rays (i) In the x-ray tube explain what process occurs at the filament? (2 marks) (ii) If the electrons hit the tungsten target with an energy of 75 keV, calculate the potential difference between the filament and the tungsten target. (5 marks) (c) What is the approximate wavelength for an x-ray? Using this value determine the approximate energy that an x-ray will have. (3 marks) (d) Why can x-rays ionise materials through which they travel? (2 marks) Physical Constants Acceleration due to gravity 9.81 m s2 g + 30% 1 <
