refrangibility การใช้
- For Newton, the prism is immaterial to the existence of colour, as all the colours already exist in white light, and the prism merely fans them out according to their refrangibility.
- In 1758 he published an " Account of some experiments concerning the different refrangibility of light " ( " Swedish physicist, Samuel Klingenstierna ( 1698 1765 ), had pointed out that Newton's law of dispersion did not harmonize with certain observed facts, he began experiments to settle the question.
- Goethe's starting point was the supposed discovery of how Newton erred in the prismatic experiment, and by 1793 Goethe had formulated his arguments against Newton in the essay " 躡er Newtons Hypothese der diversen Refrangibilit鋞 " ( " " On Newton's hypothesis of diverse refrangibility " " ).
- In an " Experimentum crucis " or " critical experiment " ( Book I, Part II, Theorem ii ), Newton showed that the color of light corresponded to its " degree of refrangibility " ( angle of refraction ), and that this angle cannot be changed by additional reflection or refraction or by passing the light through a coloured filter.
