... In order to explore the structure of crystals we require waves which interact with
atoms and which have a wavelength comparable with the interatomic spacing in
crystals ; that is , we require a wavelength of the order of 1 A ( = 10 - 8 cm ) .

00 A . The wavelength of the CuKai line is 1 . 540 A . In the first order ( n = 1 )
reflection from ( 100 ) planes 0 = sin - ( 1 . 54 / 8 . 00 ) = 11 . 1° . As the
wavelength is decreased , the angle is decreased : for gamma - rays glancing
angles must be ...
