Diffraction is an optical effect which can limit the total resolution of your photography-- no matter how many megapixels your camera may have. Ordinarily light travels in straight lines through uniform air, however it begins to disperse or "diffract" when squeezed through a small hole (such as your camera's aperture).

A wave spreads out (noticeable diffraction) when the size of the slit is comparable to or smaller than the wavelength. ... When waves reach a narrow slit, the water in the slit vibrates like a point source. The waves thus sent out from secondary sources along the slit are nearly in-phase when arriving any point in the...

Diffraction manifests itself in the apparent bending of waves around small obstacles and the spreading out of waves past small openings. ... Diffraction reveals the geometry of the diffracting object.

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 to the size of the opening. If the opening is much larger than the light's wavelength, the bending will be almost unnoticeable.

To understand diffraction we have to consider what happens when a wave interacts with a single particle. The particle scatters the incident beam uniformly in all directions.

Diffraction of Light ... The wave nature of light leads to two very important properties: refraction, where the direction of light propagation is altered at the boundary between media of different densities, and diffraction, which has among its consequences that light can "bend around corners".

Diffraction is the bending of light as it passes the edge of an object. An example of this property is the shadow. If observed carefully, the edges of shadows are not solid, but slightly fuzzy.
