Angle Of Extinction (Noun)
Meaning
The angle from its axis that a crystal must be rotated before appearing maximally dark when viewed in polarized light.
Classification
Nouns denoting two and three dimensional shapes.
Examples
- The angle of extinction is a characteristic property of a crystal that can be used to identify its composition and structure.
- By measuring the angle of extinction, geologists can determine the orientation of the crystal lattice within a rock sample.
- The angle of extinction is typically measured using a polarizing microscope, which allows the crystal to be rotated while being observed in polarized light.
- In order to determine the angle of extinction, the crystal must be rotated until it appears maximally dark when viewed in polarized light.
- The angle of extinction is an important parameter in the study of crystal optics, as it provides information about the crystal's refractive indices and lattice structure.
