Definition

1. Verb:
   • To undergo or cause diffraction: To cause (light, sound, or other waves) to spread out and bend around obstacles or through openings, resulting in interference patterns.

Usage

• The verb "diffract" describes the physical process where waves change direction as they pass through an aperture or around an edge. It is primarily used in scientific contexts, especially in physics and optics.
• It is a transitive verb, typically taking a direct object (e.g., ). It can also be used intransitively (e.g., ).

Examples

• Transitive use:
  • A finely ruled grating can diffract a beam of light into its component colors.
  • The crystal's atomic lattice diffracted the X-rays, producing a characteristic pattern.
• Intransitive use:
  • When passing through a narrow slit, sound waves diffract and spread into the shadow region.

Advanced Usage

• "to be diffracted by": This passive construction is common when describing the wave as the primary subject.
  • The radio signals were diffracted by the mountain range, allowing reception in the valley.

Variants and Related Words

• Diffraction (noun): The process or phenomenon of diffracting waves.
  • The diffraction of light through a pinhole creates a circular pattern.
• Diffractive (adjective): Relating to or involving diffraction.
  • The microscope uses diffractive optics to enhance the image.

Synonyms

• Scatter (in a specific wave context): To cause waves to deviate from a straight path.
• Disperse (in a specific wave context): To spread light or other radiation over a range of directions.
