What is Fringes and interfringe?

Also known as: interference fringes · interfringe

Definition 22.13 High School Physics · Chapter 22 — Light as a Wave: Diffraction and Interference

The pattern’s alternating bright and dark bands are its interference fringes; the distance ii between consecutive bright centers is the interfringe.

Intensity across the screen in Young’s experiment: fringes i = D/a apart, under a schematic overall envelope.
Intensity across the screen in Young’s experiment: fringes i=λD/ai = \lambda D/a apart, under a schematic overall envelope.
