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.
Diffraction refers to various phenomena which occur when a wave encounters an
obstacle or a slit. In classical physics, the diffraction phenomenon is described ...
Light bends when it passes around an edge or through a slit. This bending is
called diffraction. You can easily demonstrate diffraction using a candle or a
Diffraction. Diffraction manifests itself in the apparent bending of waves around
small obstacles and the spreading out of waves past small openings.

Definition: A modification which light undergoes, as it passes by the edges of opaque bodies or through narrow slits. The rays appear to be deflected, producing fringes of parallel bright and dark bands. Definition Copyright ©1989 CRC Press... More »
Diffraction is the slight bending of light as it passes around the edge of an object.
The amount of bending depends on the relative size of the wavelength of light ...

Diffraction of light occurs when a light wave passes by a corner or through an

Why do we have to draw lines at right angle to measure path difference, instead

diffraction of light were first conducted between the late seventeenth and early ...
