Augustin-Jean Fresnel


This French physicisit created a special lens (the fresnel lens) that has multiple parts and is used in light houses and flat screen projection systems, traffic lights, and solar collectors. Not only did he create this lens, he also worked on interference effects, diffraction, and optical lens systems. He was the first to show that light is a transverse wave by conducting experiments involving the polarization and interference of light.
