These colors, known as interference colors, result from the unequal transmission by the analyzer of the component wavelengths of the white light. 3, record 2, English, - interference%20color

"Les corps des systèmes autres que le système cubique agissent sur la lumière polarisée": ils la décomposent en deux rayons vibrant dans deux plans perpendiculaires, mais que le nicol analipeur amène à vibrer dans le même plan. Les deux vibrations peuvent alors interférer: pour la lumière du jours certaines couleurs s'annulent alors, les autres se combinent en une couleur composée et la plaque mince apparaît colorée: on a des "teintes de polarisation". 1, record 2, French, - teinte%20de%20polarisation
