An x-ray tube is operated at 40600 V.
a) Calculate the minimum wavelength of the radiation emitted by this tube.
b) If this radiation is directed at a crystal, the first-order maximum in the reflected radiation occurs when the angle of incidence is 2.85o. What is the spacing between reflecting planes in the crystal?
