The spacing of one set of crystal planes in NaCl (table salt) is d = 0.282 nm. A monochromatic beam of X-rays produces a Bragg maximum when its glancing angle with these planes is θ = 7o. Assuming that this is a first order maximum (n = 1), find the wavelength of the X-rays. What is the use of contrast agents in x-ray radiography? Give 2 exemplary contrast agents. Thankss
