Web11 Earlier formulae for the rotatory dispersion of quartz The phenomenon of optical activity was discovered in the year 1811 by Arago in crystals of quartz cut perpendicular to the optic axis. Soon afterwards, Biot showed that the rotatory power in the visible region of the spectrum varies inversely as the square of the wavelength, i.e. p = k/A2. black agriche

WebIn 1812, Biot turned his attention to the study of optics, particularly the polarization of light. Prior to the 19th century, light was believed to consist of discrete packets called corpuscles. During the early 19th century, many scientists began to disregard the corpuscular theory in favor of the wave theory of light. Biot began his work on ... WebBiot began his work on polarization to show that the results he was obtaining could appear only if light were made of corpuscles. His work in chromatic polarization and rotary polarization greatly advanced the field of optics, although it was later shown that his findings could also be obtained using the wave theory of light (Frankel). ...
