A; You are measuring the lattice constant (the distance between planes of atoms) of a sample crystal using X-ray diffraction. The crystal structure is known to be SC or simple cubic. Your X-ray tube produces X-rays with a wavelength of 0.630 nm. You observe the first diffraction peak at an angle of 28.5°. What is the lattice constant of the crystal? _____??? B: Suppose that at least 21.5 eV is needed to free an electron from a particular element, i.e.,...
