Diffraction -- from Eric Weisstein

WebbDiffraction is a phenomenon by which wavefronts of propagating waves bend in the neighborhood of obstacles. Diffraction around apertures is described approximately by a mathematical formalism called scalar diffraction theory. Diffraction problems are among the difficult encountered in optics, and exact rigorous solutions are quite rare.

The … In physics, the wavefront of a time-varying wave field is the set (locus) of all points having the same phase. The term is generally meaningful only for fields that, at each point, vary sinusoidally in time with a single temporal frequency (otherwise the phase is not well defined). Wavefronts usually move with time.

"WebbSpherical waves are generally seen as sound waves and light waves. They have a point source and the waves formed, move forward in all directions. A plane wave moves forward in only one direction. A true plane wave ceases to exist in reality. This is because then it would require filling the entire space, which is not seen in experiments.
