What is diffraction?


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.

Change in the directions and intensities of a group of waves after passing by an obstacle or through an aperture whose size is approximately the same as the wavelength of the waves.
Diffraction photography was used in spectroscopy to help record the chemical composition of objects studied by astronomers and was also used to determine the composition of different
The colors are due to the wavelength dependence of diffraction. As for the "X" and the horizontal line, those are due to the edges of the feature(s) from which the light
Diffraction:1:when light passes sharp edges or goes through narrow slits the rays are deflected
1 Additional Answer
Ask.com Answer for: what is a diffraction
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.
the bending of waves, especially sound and light waves, around obstacles in their path.
