Moiré Pattern of Two Equally Spaced Circular Ring Patterns
Moiré Pattern of Two Equally Spaced Circular Ring Patterns
The Moiré pattern formed using two displaced equally spaced circular ring patterns illustrates the interference fringes produced by interfering two spherical waves. The spacing of the Moiré pattern depends on the separation between the centers of the two circular ring patterns, just like the spacing of interference fringes depends upon the separation between the two point sources. This Demonstration shows the shape of the interference fringes in a plane containing the two point sources.
