diffract

listen to the pronunciation of diffract
Englisch - Englisch
To undergo diffraction
To cause diffraction
{f} break up, bend (as in light or sound waves)
undergo diffraction; "laser light diffracts electrons"
undergo diffraction; "laser light diffracts electrons
To break or separate into parts; to deflect, or decompose by deflection, a&?; rays of light
to bend light or sound waves as they pass around something or through a hole refract
diffractively
In a diffractive manner; by means of, or accompanied by diffraction
diffraction
The apparent bending of waves around small obstacles and the spreading out of waves past small openings
diffraction
a change in the direction of a wave that is caused by the wave moving past or hitting an obstacle
diffraction
The bending of waves around the edges of objects In connection with a blast wave impinging on a structure, diffraction refers to the passage around and envelopment of the structure by the blast wave Diffraction loading is the force (or loading) on the structure during the envelopment process
diffraction
Spreading of waves around obstacles. It occurs with water waves, sound, electromagnetic waves (see electromagnetic radiation), and small moving particles such as atoms, neutrons, and electrons, which show wavelike properties. When a beam of light falls on the edge of an object, it is bent slightly by the contact and causes a blur at the edge of the shadow of the object. Waves of long wavelength are diffracted more than those of short wavelength
diffraction
Diffraction, the deviation of light from rectilinear propagation, is a characteristic of wave phenomena which occurs when a portion of a wave front is obstructed in some way When various portions of a wave front propagate past some obstacle, and interfere at a later point past the obstacle, the pattern formed is called a diffraction pattern
diffraction
The spreading out of light as it passes over a sharp edge, or through a narrow (in terms of wavelength) slit The obstructions in the tube of a telescope can give rise to such effects, thereby reducing image contrast and giving rise to rings and 'spikes' around stellar images, which should be purely point-like
diffraction
The process whereby RF signals or sound waves are, in certain circumstances, deflected from their normal straight-line path by physical objects
diffraction
The deflection and decomposition of light in passing by the edges of opaque bodies or through narrow slits, causing the appearance of parallel bands or fringes of prismatic colors, as by the action of a grating of fine lines or bars
diffraction
Departure from perfect sharpness of the shadow edge of an illuminated object Limits the minimum size of a focussed spot See Huygens' principle
diffraction
A situation where waves curve or spread-out as they pass through an opening or move around a barrier Click here to see water waves diffracting (movie) Back to Top Back to Wave Index
diffraction
{i} process of breaking up or bending waves (especially light or sound waves)
diffraction
Periodic scattering of moving objects when they collide with an orderly pattern of fixed objects Diffraction always follows Bragg's Law {n*Wavelength=2*Spacing of fixed objects*sin(angle of scattering)} This periodic scattering is useful in determining the spacing of the fixed objects since all other variables in the equation are know In Electron Microscopy the spacings being determined are those between atoms in a lattice or crystal
diffraction
Light interference, due to light interaction with an physical edge The size of the edge must be the same as the light wavelength in order to produce the interference Astronomers observe light in specific wavelengths with a diffraction grating, a glass surface with fine grooves cut into it The groove dimensions correspond to wavelengths of light, around 500 nanometers (green) +/- 150 nanometers (blue to red) Astronomers use the grating to "spread" light into its component colors, to learn about a star's temperature, composition, speed, and distance from Earth
diffraction
This is the process that makes holograms work, and refers to the bending of light as it passes through very small openings Diffraction "patterns" use light wave interference to intricately control the intensity distribution of the light transmitted, so that 3-D, animated images can be formed   This is different from refraction, which is the bending of light when it passes from one medium to another, like air to glass
diffraction
The phenomenon occurring when water WAVES are propagated into a sheltered region formed by a BREAKWATER or similar barrier that interrupts a portion of the otherwise regular train of WAVES, resulting in the multi-directional spreading of the WAVES
diffraction
  The deviation of an electromagnetic wavefront from the path predicted by geometric optics when the wavefront interacts with, i e , is restricted by, a physical object such as an opening (aperture) or an edge   (188) Note: Diffraction is usually most noticeable for openings of the order of a wavelength   However, diffraction may still be important for apertures many orders of magnitude larger than the wavelength
diffraction
The deviation from linear propagation that occurs when light passes a small object or opening This phenomenon is significant only when the object or opening is on the order of the wavelength of light, between 380 and 780 nanometers for human vision For this reason, diffraction effects are ignored in most rendering algorithms, since most modeled geometry is on a much larger scale
diffraction
modification of the behavior of a light wave resulting from limitations of its lateral extent by an obstacle For example, the bending of light into the "shadow area" behind a particle
diffraction
The bending of light as it passes through a small slit or opening When we study the diffraction of sunlight, we see a rainbow of colours
diffraction
The spreading out of waves when they pass through a gap or round the edge of an obstacle
diffraction
The bending of a wave around objects placed in its path
diffraction
Process affecting wave propagation, by which wave energy is radiated normal to the direction of wave propagation into the lee of an island or breakwater
diffraction
Spreading or bending of a wave upon passing around an obstacle or through a narrow opening
diffraction
Slight bending of light waves around a sharp edge that is a result of lights wave nature
diffraction
The breaking up of an electromagnetic wave as it passes a geometric structure (e.g. a slit), followed by reconstruction of the wave by interference
diffraction
The spreading of light as it passes a sharp edge of an opaque object
diffraction
The spreading of a wave disturbance into a region behind an obstruction
diffraction
A phenomenon that occurs whenever a wave is obstructed in any way Often diffraction fringes can be seen when a small aperature or object blocks light waves Scientists use diffraction gratings to break up light into many wavelengths
diffraction
The result of light waves interfering with other after passing through a narrow aperture, causing them to bend or spread
diffraction
when light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands
