Bragg condition’s

The diffraction condition can be
written in vector form
*
*
**k** - is the
incident wave vector
**k’ **- is the
reflected wave vector
**G** - is a
reciprocal lattice vector such that where

l2**k****∙****G** + *G**2** = 0
*

l**G** = **∆****k** = **k **- **k’
**

the
diffraction condition is met
