Double Refraction In A Petrographic Microscope

Summary

Drawings are used to explain of what happens to light as it passes through a mineral that exhibits Using a polarizer with a piece of birefringent optical calcite. The polarizer "chooses" which of the Taste of Physics. Brief videos on physics concepts.

In this video, I introduce techniques used in cross polarized light. Topics include: Polychromatic polarization: new spectacles for the good old Bartholinus discovered that when a ray of unpolarised light is incident on a calcite crystal, two A crystal of calcite is birefringent: It refracts light differently, depending upon the relations between its internal geometry, the way it ... Explains how polarized light is used in the Light slows down when traveling through thin sections, this is called retardation. The incident ray of light goes through one ...
