one hundred ce) undertook one of several 1st quantitative experiments of the refraction of light as it passes from one transparent medium to another, tabulating pairs of angles of incidence and transmission for mixtures of various media.

, offered a regulation of reflection and talked over the propagation of light rays in straight strains. Ptolemy (
Thomas Younger's sketch of the double-slit experiment showing diffraction. Younger's experiments supported the idea that light is made of waves. The wave theory predicted that light waves could interfere with each other like audio waves (as pointed out about 1800 by Thomas Younger). Young showed by means of a diffraction experiment that light behaved as waves. He also proposed that distinct colors have been due to diverse wavelengths of light and stated colour eyesight with regards to three-coloured receptors in the attention.
