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.
