O QUE SIGNIFICA DIFFRACTION PATTERN EM INGLÊS
Difração
A difração refere-se a vários fenômenos que ocorrem quando uma onda encontra um obstáculo ou uma fenda. Na física clássica, o fenômeno de difracção é descrito como a interferência das ondas de acordo com o princípio de Huygens Fresnel. Esses comportamentos característicos são exibidos quando uma onda encontra um obstáculo ou uma fenda que é comparável em tamanho ao seu comprimento de onda. Efeitos semelhantes ocorrem quando uma onda de luz viaja através de um meio com um índice de refração variável, ou quando uma onda de som viaja através de um meio com impedância acústica variável. A difração ocorre com todas as ondas, incluindo ondas sonoras, ondas de água e ondas eletromagnéticas, como luz visível, raios-X e ondas de rádio. Uma vez que os objetos físicos têm propriedades semelhantes a ondas, a difracção também ocorre com a matéria e pode ser estudada de acordo com os princípios da mecânica quântica. O cientista italiano Francesco Maria Grimaldi inventou a palavra "difração" e foi o primeiro a registrar observações precisas do fenômeno em 1660.
definição de diffraction pattern no dicionário inglês
A definição de padrão de difracção no dicionário é o padrão distintivo de franjas claras e escuras, anéis, etc., formados por difração.
