Exercise 1: Calculate the minimum-wavelength x-ray that can be produced when a target is struck by an electron that has been accelerated through a potential difference of 16.0 kV and1.10 ✕ 10 2 kV. Exercise 2: When x-rays of wavelength of 0.129 nm are incident on the surface of a crystal having a structure similar to that of NaCl, a first-order maximum is observed at 8.15°. Calculate the interplanar spacing based on this information. nm
Exercise 3: X-rays of wavelength 0.200 nm are reflected from a certain crystal, and the first-order maximum occurs at an angle of 14.2°. What value does this give for the interplanar spacing of the crystal? nm
