Bragg's law

In physics, Bragg's Law (or "Wulff -Bragg's condition" in post-Soviet countries, a special case of Laue diffraction) gives the angles for coherent and incoherent scattering from a crystal lattice. When X-rays are incident on an atom, they make the electronic cloud move as does any electromagnetic wave. The movement of these charges re-radiates waves with the same frequency, blurred slightly due to a variety of effects; this phenomenon is known as Rayleigh scattering (or elastic scattering). The scattered waves can themselves be scattered but this secondary scattering is assumed to be negligible.

A similar process occurs upon scattering neutron waves from the nuclei or by a coherent spin interaction with an unpaired electron. These re-emitted wave fields interfere with each other either constructively or destructively (overlapping waves either add up together to produce stronger peaks or are subtracted from each other to some degree), producing a diffraction pattern on a detector or film. The resulting wave interference pattern is the basis of diffraction analysis. This analysis is called Bragg diffraction.

Meu caro amigo me perdoe, por favor
Se eu não lhe faço uma visita
Mas como agora apareceu um portador
Mando notícias nessa fita
Aqui na terra 'tão jogando futebol
Tem muito samba, muito choro e rock'n'roll
Uns dias chove, noutros dias bate sol
Mas o que eu quero é lhe dizer que a coisa aqui tá preta
Muita mutreta pra levar a situação
Que a gente vai levando de teimoso e de pirraça
E a gente vai tomando que, também, sem a cachaça
Ninguém segura esse rojão
Meu caro amigo eu não pretendo provocar
Nem atiçar suas saudades
Mas acontece que não posso me furtar
A lhe contar as novidades
Aqui na terra tão jogando futebol
Tem muito samba, muito choro e rock'n'roll
Uns dias chove, noutros dias bate sol
Mas o que eu quero é lhe dizer que a coisa aqui tá preta
É pirueta pra cavar o ganha-pão
Que a gente vai cavando só de birra, só de sarro
E a gente vai fumando que, também, sem um cigarro
Ninguém segura esse rojão
Meu caro amigo eu quis até telefonar
Mas a tarifa não tem graça
Eu ando aflito pra fazer você ficar
A par de tudo que se passa
Aqui na terra 'tão jogando futebol
Tem muito samba, muito choro e rock'n'roll
Uns dias chove, noutros dias bate sol
Mas o que eu quero é lhe dizer que a coisa aqui tá preta
Muita careta pra engolir a transação
E a gente tá engolindo cada sapo no caminho
E a gente vai se amando que, também, sem um carinho
Ninguém segura esse rojão
Meu caro amigo eu bem queria lhe escrever
Mas o correio andou arisco
Se permitem, vou tentar lhe remeter
Notícias frescas nesse disco
Aqui na terra 'tão jogando futebol
Tem muito samba, muito choro e rock'n'roll
Uns dias chove, noutros dias bate sol
Mas o que eu quero é lhe dizer que a coisa aqui tá preta
A Marieta manda um beijo para os seus
Um beijo na família, na Cecília e nas crianças
O Francis aproveita pra também mandar lembranças
A todo o pessoal
