Interference Colors - Essay Example

Interference Colors An interference color is a color that is exhibited by a segment of an anisotropic mineral under cross-polarized light. Impedance delivers this color between the two beams created as light goes through an anisotropic mineral, the quick beam, and the moderate beam. Intervention between the two beams produces colors diverse from the source light by productive impedance since the period of the fast beam is moved with respect to the moderate beam. The act of light slowing down as it passes through a substance is measured using a number referred to as the index of reflection.

Interference colors are thus an effect that emanates because different substances have different index of reflection (Ulery, & Drees 185). Birefringence is the variation in the indices of reflection. Interference colors can be understood by utilizing color charts that are contained in most of the course readings. If the thickness of an area is known, then the birefringence can be determined from the interference color. Most extreme birefringence can be analytic of a mineral when utilized with different properties.

If the thin segment contains a known mineral, with a confined scope of birefringence, then the interference color can be utilized to focus the thickness of the segment (Haldar, & Josip 50). Standard slender areas are 30 microns thick. Meager segments thicker than 30 microns will deliver higher interference colors. Interference colors rehash. Nevertheless, high order colors can be recognized from lower order ones by watching the margins between gemstones or those crystals at the edges of the minor segment.

These zones of a thin area are frequently more slender and will demonstrate an arrangement of lower interference colors.Works CitedHaldar, S K, and Josip Tišljar. Introduction to Mineralogy and Petrology.
