When a wave goes past an obstacle it is slightly bent into the area that should be in shade (the classically forbidden zone), this is also seen at a slit, when the light is spread out. This effect is appriciable when the object is approximately the same sive as the wavelength.
This can only be explained using Quantum Electrodynamics. If a screen is placed behind a slit the light makes a larger band than would be expected this is because each photon of light as to be considered to have taken every possible path from the source to the screen. Each path as a probability amplitude associated with it. The probabilities are added in a strang way the lenghth of the probability shown as an arrow are spun at the same rate as the waves frequence these are added by measuring the length from one arrow head to the other if both tails are rotating around the same centre. If both arrows where pointing in the same direction then the probability would be zero, if both arrows where pointing in opposite directions then the probability is squared. Without going into to much detail, the smallness of the slit stops some of the probability amplitude being cancelled out in the forbidden zone.
What else can I help you with?
What is the bending of waves around the edge of a barrier called?
Diffraction. It occurs when waves encounter an obstacle or aperture and bend around it, spreading out into the region behind the barrier.
What is diffraction and how does the amount of diffraction depend on wave length?
Diffraction is the bending of waves around obstacles and the spreading of waves as they pass through apertures. The amount of diffraction depends on the wavelength of the wave: shorter wavelengths produce less diffraction, while longer wavelengths produce more pronounced diffraction effects.
What is another term for fraunhofer diffraction?
Another term for Fraunhofer diffraction is far-field diffraction. This type of diffraction occurs when the distance between the diffracting object and the screen observing the diffraction pattern is much greater than the dimensions of the diffracting object.
What is the relationship between the diffraction angle and the wavelength of light in a diffraction grating experiment?
In a diffraction grating experiment, the relationship between the diffraction angle and the wavelength of light is described by the equation: d(sin) m. Here, d is the spacing between the slits on the grating, is the diffraction angle, m is the order of the diffraction peak, and is the wavelength of light. This equation shows that the diffraction angle is directly related to the wavelength of light, with a smaller wavelength resulting in a larger diffraction angle.
Bending a wave around a barrier is called?
It is called diffraction.
What is the difference between x-ray diffraction and electron diffraction?
Although many people would not fully understand this electron diffraction gives you only one plane. X-Ray diffraction will give you a scattering of all the planes in one measurement.

fresnel diffraction and fraunhoffer diffractions

How does diffraction work for kids?
Diffraction is when light waves bend around obstacles or pass through small openings, creating patterns of light and dark spots. It happens because light waves spread out as they travel, leading to interference patterns. Kids can understand diffraction by shining a laser pointer through a small slit or around edges to see how the light bends and creates patterns on a wall or surface.
How does the phenomenon of light grating contribute to the understanding of diffraction patterns?
Light grating, which is a device that splits light into its component colors, helps scientists study diffraction patterns by creating interference patterns that show how light waves interact with each other. This allows researchers to better understand how light behaves when it passes through small openings or around obstacles, leading to insights into the nature of diffraction.
What is the basic principle of x- ray diffraction?
The idea is that, due to the small wavelength of X-rays, atoms can serve as a diffraction grid - causing diffraction patterns. (If you don't know about diffraction, I suggest you search in the questions for "diffraction", or ask a separate question for diffraction.) Crystals are good for this, because of their regular structure.
