Meaning and Definition
The distinctive arrangement of light or wave intensity produced when waves (especially light or electrons) encounter an obstacle or pass through a slit, creating interference effects.
In materials science, the characteristic pattern produced on a detector when a beam of radiation (X-rays, electrons, neutrons) is scattered by the ordered atomic structure of a crystal, used to determine the material's structure.

FAQ
Frequently Asked Questions
Not exactly. A spectrum separates light by wavelength/colour. A diffraction pattern shows the spatial intensity distribution caused by wave interference from obstacles or regular structures, which can be colour-dependent but is fundamentally about interference in space.
Yes, for visible light. Common examples include the coloured patterns seen on a CD or DVD surface, the fuzzy edges of shadows, or the pattern from light passing through fine fabric like an umbrella.
Diffraction refers to the spreading of waves when they encounter an obstacle or aperture. Interference is the superposition of waves. A 'diffraction pattern' is specifically the pattern resulting from the diffraction of waves, which inherently involves interference between different parts of the same wavefront.
They are a powerful non-destructive analytical tool. In crystallography, the pattern acts like a unique fingerprint, allowing scientists to deduce the 3D arrangement of atoms in a material, which is crucial for developing new drugs, materials, and understanding geological samples.
