First-order
Bragg reflection from a certain crystal occurs at an angle of
|
Solution: Click For PDF Version From the lattice we note that the interplanar separation in terms of the unit cell size
will be
The angle of
incidence is
The Bragg equation is

see the figure. The
wavelength of the x rays is 0.261 nm.
Assuming that the scattering is from the
dashed planes shown, we
have to find the unit cell size
.
