Isaac Newton e a dupla refração da luz

Abstract: Este artigo apresenta uma abordagem histórica sobre a dupla refração da luz, especialmente sobre as ideias de Isaac Newton. Inicialmente, são discutidos os estudos de Erasmus Bartholinus, que descobriu o fenômeno e o descreveu em 1669, e de Christiaan Huygens, que elaborou um modelo explicativo baseado em uma concepção vibracional para a luz em seu Tratado sobre a luz (1690). Em seguida, analiso em detalhes o conceito de lados da luz elaborado por Newton para explicar o fenômeno, descrito nas "Questões" de seu… Show more

“…3,4 , or in the dentistry for the study of maxillary stresses distributions due to chewing forces 5,6 . This huge interest in photoelasticity comes from the transparency and high flexibility the photoelastic materials show, which allows the observation of the phenomenon of temporary double refraction by polarization, or birefringence, first described by Erasmus Batholinus in the 19th century 7,8 and associated with the state of stress and deformation of the material by David Brewster 9 . Photoelasticity is a subarea of optics that studies the internal effects caused by external forces on samples of photoelastic materials using polarized light 10,11 .…”
