What type of crystals did Fresnel study in relation to light refraction?

  • Quartz

  • Calcite

  • Diamond

  • Sapphire

Answer

Fresnel studied calcite crystals in relation to light refraction. He generalized the direction-speed-polarization relation for calcite, which helped him account for the directions and polarizations of refracted rays in doubly-refractive crystals of the biaxial class.
