Definitions

  1. The process where waves, like light or sound, change direction as they encounter edges or openings leads to the formation of interference patterns
  2. When waves travel through slits or are obstructed, they bend and spread out, resulting in unique patterns of interference
  3. The bending and spreading of waves occurs as they pass through openings or around obstacles, resulting in characteristic interference patterns

Etymology: "Diffracted" is the past tense and past participle of "diffract," so its story belongs to the verb. The verb comes from Latin "diffringere," meaning "to shatter" or "to break into pieces," built from "dis-," "apart," and "frangere," "to break." Its past participle, "diffractus," gave English the stem it uses today. The original sense is strikingly physical. A Latin speaker describing something diffringed was describing an object reduced to fragments, not a beam of light bending around an edge. The meaning moved from breaking solid things apart to splitting light and waves into their component parts. When a wave passes a gap or an obstacle and spreads out behind it, the wave has, in a sense, been broken up and redirected, and that is the idea the modern physics term carries.
