Diffraction at an edge

Article no: P1412301

Principle

If a plane wave meets a straight edge of an obstacle, the edge acts as the starting point of secondary waves according to Huygens' Principle. These overlap with the wave part passing the edge undisturbed. Interference of both bundles results in a sequence of light and dark interference fringes in the passband.

Benefits
