Definition
- Adjective:
- (Physics, of a wave, especially light) Vibrating or oscillating in only one specific direction or plane. This describes a wave whose electric field vector is confined to a single plane along the direction of propagation.
Usage
- The term is primarily used in the context of optics and wave physics to describe the state of electromagnetic radiation, most commonly light.
- It is typically used attributively (before a noun) to describe the type of wave or light.
- Common Collocation: Almost exclusively used with "light" as in "plane-polarized light."
Examples
- Adjective:
- Sunglasses often use lenses that only allow plane-polarized light to pass through, reducing glare.
- The crystal filter converted the ordinary light beam into a beam of plane-polarized light.
- To observe the effect, the sample must be illuminated with plane-polarized light.
Advanced Usage
- Scientific Context: The concept is fundamental in techniques like polarized light microscopy, optical mineralogy, and LCD (Liquid Crystal Display) technology, where controlling the plane of polarization is crucial.
- Contrast with Unpolarized Light: Ordinary light (e.g., from the sun or a lamp) is unpolarized, meaning its waves vibrate in all possible planes perpendicular to the direction of travel. "Plane-polarized" light is the result of filtering out all but one plane of vibration.
Variants and Related Words
- Polarize (verb): To cause (a wave, especially light) to vibrate in a single plane.
- Polarization (noun): The process or state of being polarized.
- Polarizer (noun): A device that produces plane-polarized light from light of mixed polarizations.
- Linearly Polarized: A synonym for "plane-polarized" in technical contexts.
Synonyms
