If your solution does not contain the answer to section a), the latter sections will not be considered. carbon target D/2 -L-R L a) Use geometry of the given figure above to show, D Rsin(- 2R D L-R+ Rcos( 2 R $ = = arctan Here o is our deviation angle in our electron diffraction experiment. b) Now, set L to R to and express 0 in terms of D. Hint : Use the relation between Bragg angle,0and deviation angle,p.
