What Is a Diffraction?

Answer

Diffraction is defined as the various phenomena which occur when a wave encounters an obstacle. In classical physics, the diffraction phenomenon refers to the apparent bending of waves around small obstacles and the spreading out of waves past small openings.

NOUN [PHYSICS.]
1.
the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow.
2.
the bending of waves, especially sound and light waves, around obstacles in their path.

Diffraction refers to the process by which a beam of light or other system of wave is spread out as a result of passing through a narrow aperture or across an edge. The waves are typically accompanied by interference between the wave forms produced.
