Definition

1. Noun:
   • Splitting a ray into two parallel rays polarized perpendicularly: In optics, "double refraction" refers to the phenomenon where a single incident light ray splits into two separate rays as it passes through certain anisotropic materials. These two rays are polarized in mutually perpendicular planes and may travel at different speeds.

Examples of Usage

• Noun:
  • Calcite crystals exhibit strong double refraction. (Calcite crystals show a clear splitting of light into two rays.)
  • The scientist studied the double refraction in the mineral sample. (The researcher investigated the light-splitting property within the mineral specimen.)

Advanced Usage

• "Birefringence": This is a technical synonym often used interchangeably with "double refraction" in scientific contexts, specifically referring to the material's property.
  • The birefringence of the quartz was measured using a polarizing microscope. (The double-refractive property of the quartz was quantified.)

Variants and Related Words

• Birefringent (adj): Describing a material that causes double refraction.
  • The birefringent material created two distinct images. (The double-refracting substance produced two separate images.)

Synonyms

• Birefringence: The property of having two different refractive indices.
