>Lattices  constructed by a set vector R normally known as direct lattice or crystal lattice
> A translation lattice vector represents an infinite lattice points

R = n1a1 + n2a2 + n3a3, for all integer.

Definition reciprocal lattice, K
>A reciprocal lattice is define by a set of vector K that satisfy eqn:

K = m1b1 + m2b2 + m3b3;
where m1, m2 and m3 are all integers

1. Let the head of the vector meet the origin of the reciprocal lattice. 

2. From the tail of this vector, draw a sphere of radius 1/lambda. Such a sphere is called Ewald sphere. 

3. All reciprocal lattice points lying on the surface of the Ewald sphere satisfy Bragg law. 

4. The direction of the diffracted beam is determined by drawing a vector joining the origin of the reciprocal lattice and the reciprocal lattice points on the surface of the Ewald sphere]]> 2018-05-13 19:08:50 UTC https://padlet.com/ezzasyuhada/Group5/wish/260260284 https://padlet.com/ezzasyuhada/Group5/wish/260270323 2018-05-13 20:46:22 UTC https://padlet.com/ezzasyuhada/Group5/wish/260270323 Crystal Lattices in Real Space https://padlet.com/ezzasyuhada/Group5/wish/261806183 2018-05-18 04:37:25 UTC https://padlet.com/ezzasyuhada/Group5/wish/261806183
