Unformatted text preview: lead is 4.950 . If Xrays with = 1.936 are diffracted by this set of planes, calculate the scattering angles 2 at which firstorder, secondorder, thirdorder, and fourthorder ( n = 1, 2, 3, 4) will be observed. (47) Braggs equation contains sin , where 2 is the angle between the incident Xray beam and diffracted Xray beam. Since sin 1, this places a limit on what can be observed in a crystal. (a) Use the Bragg equation and deduce the limitation on dspacings between planes of atoms when Cu K Xradiation is used ( = 1.54178 ), when Mo K Xradiation is used ( = 0.71069 )....
