Problems are listed in approximate order of difficulty. A single dot (•) indicates straightforward problems involving just one main concept and sometimes requiring no more than substitution of numbers in the appropriate formula. Two dots (••) identify problems that are slightly more challenging and usually involve more than one concept. Three dots (•••) indicate problems that are distinctly more challenging, either because they are intrinsically difficult or involve lengthy calculations. Needless to say, these distinctions are hard to draw and are only approximate.
• When X-rays of wavelength λ = 0.20 nm are reflected off the face of a crystal, a Bragg maximum is observed at a glancing angle of θ = 17.5°, with sufficient intensity that it is judged to be first order. (a) What is the spacing d of the planes that are parallel to the face in question? (b) What are the glancing angles of all higher order maxima?
