|
Scattering
|
the interaction of an obstacle and some form of wave
|
|
|
|
Diffraction
|
If obstacles are periodically arranged, at distances comparable to wavelength, wave interference will cause enhancement & suppression of intensities in certain direction
|
|
|
|
Huygens Principle
|
All points on primary Wavefront can be considered as point Sources of secondary, Spherically shaped Wavelets
|
Wave front propagation over time
|
|
|
Bragg's condition
|
slit from experiment is replaced by obstacles
each plane acts like a mirror find direction of high intensities relative to incoming radiation |
|
|
|
Bravais Lattice
|
An infinite set of discrete points with an arrangement and orientation that appears exactly the same from whichever view point
|
|
|
|
Lattice Plane
|
Any plane Containing at lease 3 points from a Bravais Lattice separated by inter planar spacing d
|
|
|
|
Miller Index
|
A series of co prime integers inversely proportional to the intercepts of the crystal face or crystallographic planes within the edges of the unit cell
|
|
|
|
Reciprocal Lattice Vector
|
Determines how the periodic Structure interacts with waves
|
|
|
|
Real space Lattice
|
Describes the periodic structure
|
|
|
|
