Diffraction definition, 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.

Diffraction Grating Physics; Diffraction Grating Physics. When light encounters an obstacle such as an opaque screen with a small opening (or aperture), the intensity distribution behind the screen can look much different than the shape of the aperture that it passed through.
Diffraction definition is – a modification which light undergoes especially in passing by the edges of opaque bodies or through narrow openings and in which the rays appear to be deflected; also : a similar modification of other waves (such as sound waves) or of moving particles (such as electrons).
diffraction grating definition: Optics a plate of glass or polished metal ruled with a series of very close, equidistant, parallel lines, used to produce a spectrum by the diffraction of reflected or transmitted light
Diffraction is a result of physics. It doesn’t matter how good your lens is; diffraction will rob sharpness at smaller apertures no matter what. Even though you cannot circumvent the laws of physics, there is one way to avoid diffraction in your photographs: use a larger aperture.
Diffraction is often confused with refraction because the words sound and are spelled in a similar way, but don’t let that put you off!. When a set of waves meet a gap or an object, they tend to spread out on the other side – this is called diffraction.. Learning hint: diffraction begins “diff” and diffraction involves waves spreading out, almost diffusing, you might say!
Diffraction refers to various phenomena that occur when a wave encounters an obstacle or a slit. It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle. In classica
‘It is a fact of physics that all light beams suffer from diffraction; it was not thought that much could be done about it.’ ‘But once the circuit elements get down to sizes close to the wavelength of light, diffraction begins to blur the circuit patterns as they are projected.’

Diffraction: A Test For Waves. Ripples on water’s surface are classified as waves. That’s because we can see the water’s surface move up and down in a repeating pattern of troughs and crests as
What Diffraction Definition Physics Is – and What it Is Not. This pattern results from diffraction much like that produced by a single slit. Although a smaller aperture will offer a bigger depth of field, the consequences of diffraction will get increasingly noticeable at extremely little apertures, reducing the total sharpness of the image.

Diffraction A wave will diffract (spread out) as it goes through a gap or past an obstacle. Note: The wavelength remains the same before and after the gap. Remember this: The nearer the slit size is to the wavelength, the more the wave will diffract. The smaller the gap the greater the diffraction. The longer the wavelength the greater the diffraction.
Diffraction. Diffraction refers to various phenomena that occur when a wave encounters an obstacle. In classical physics, the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings.
Huygens’ Principle Definition The Huygens’ principle of wave analysis basically states that: Every point of a wave front may be considered the source of secondary wavelets that spread out in all directions with a speed equal to the speed of propagation of the waves.
La diffraction est le comportement des ondes lorsqu’elles rencontrent un obstacle ou une ouverture ; le phénomène peut être interprété par la diffusion d’une onde par les points de l’objet. La diffraction se manifeste par le fait qu’après la rencontre d’un objet, la densité de l’onde n’est pas conservée contrairement aux lois de l’optique géométrique.
When waves pass through a narrow gap, they spread out. This spreading out is called diffraction. Diffraction is defined as the spreading of a wave into regions where it would not be seen if it moved only in straight lines after passing through a narrow slit or past
