Abstract

Some characteristics of Newton's philosophical method relevant to his works First Paper on Light and Colours (1672) y Opticks (1704) are discussed. It is shown from his prism experiments using different materials described in those works that it is possible that he may have carried out experiments with air prisms in water. This would have questioned the inductive conclusion that red rays are always less refracted than blue ones. Finally, and with a pedagogical intention, an experiment is reported to illustrate the result obtained depending on the material of the prism and of the medium.

Keywords: Optics; light; colours; Newton experimental philosophy.

 

Resumen

Se discuten algunas características del método de filosofía de Newton particularmente relevantes a sus trabajos First Paper on Light and Colours (1672) y Opticks (1704). Se muestra que, a partir de los experimentos con prismas de diferentes materiales descritos por Newton en esas obras, es muy probable que haya realizado experimentos con prismas de aire inmersos en agua. Esto último hubiera cuestionado la conclusión inductiva de que los rayos rojos son siempre menos refractados que los azules. Finalmente, y con un propósito pedagógico, se reporta un experimento que ilustra el resultado obtenido dependiendo del material del prisma y del medio.

Descriptores: Óptica; luz; colores; filosofía experimental de Newton.
