What is diffraction?

Answer

Diffraction occurs when a wave bends around objects. Diffraction is also said to occur when a wave spreads after it has passed through a type of gap.

Huygens' principle states that waves can spread in spheres or circles when in two-dimensional and three-dimensional space. Diffraction is the reason why a microscope is unable to be used to see much smaller details. In general, microscopes are only able to see details that are bigger than the used wavelength. Optical microscopes are unable to be used for any objects that are smaller than a micrometer. Viruses are mostly smaller than a micrometer and are usually undetected by microscopes.

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.
