  • Set contains: Polarizers, Mica Wafers, selenite, calcite samples, Benzoic Acid wafers, stressed plastic, cellophane, and corn syrup.
  • View various objects between two polarized lenses; rotate a lens to see change in color patterns.
  • Phenomenon is the result of optical rotation. Linearly polarized light rotates as it passes through these materials. Extent of rotation depends on wavelength of light, causing angular separation of colors.
