# What was Isaac Newton's contribution to optics?

What was Isaac Newton's contribution to optics? I know that he believed in the corpuscular theory of light. Did he know about the laws of reflection ad refraction?

• It took a very long time to overturn some of Newton's ideas about light. You might like to read the wiki page for Augustin-Jean Fresnel who put the final nail into the coffin of the corpuscular theory. en.wikipedia.org/wiki/Augustin-Jean_Fresnel – Lysistrata May 13 '19 at 19:21
