interference fringe
Noun: * Interference Fringe: One of the alternating light and dark bands produced by the interference of light waves. These bands are a visible pattern resulting from the constructive (bright bands) and destructive (dark bands) interference of coherent light waves, such as those that have passed through two closely spaced slits or been reflected from thin films.
The term is used primarily in the context of physics, optics, and engineering to describe the observable pattern from wave interference experiments. * The spacing between the interference fringes on the screen depends on the wavelength of the light used. * Newton's rings are a classic example of circular interference fringes created by the air gap between a lens and a flat glass plate.
- "Fringe spacing" or "fringe width": Refers to the distance between two consecutive bright fringes or two consecutive dark fringes. This is a key measurable quantity in interference experiments.
- By measuring the fringe spacing, scientists can calculate the wavelength of the light source.
- "Fringe pattern": The overall arrangement of interference fringes.
- The laser created a clear and stable fringe pattern on the detector.
- Fringe (noun): In this specific scientific context, "fringe" is often used as a shortened form of "interference fringe."
- The position of the third bright fringe was recorded.
- Interference pattern (noun phrase): The broader pattern of which interference fringes are the constituent bands.
- Diffraction fringe (noun): A band in a pattern produced specifically by diffraction, though the terms "interference fringe" and "diffraction fringe" are often linked as both phenomena involve wave superposition.
- Band (in the context of interference patterns)
- Stripe (in the context of interference patterns)
- Constructive Interference: The process that produces a bright fringe, where wave peaks align to increase intensity.
- Destructive Interference: The process that produces a dark fringe, where a wave peak aligns with a trough to cancel out the light.
- Young's double-slit experiment: A fundamental experiment that famously produces a series of equally spaced interference fringes.
- Thin-film interference: The phenomenon that creates interference fringes in soap bubbles, oil slicks, and anti-reflective coatings.
-
one of the light or dark bands produced by the interference and diffraction of light
