Change in the directions and intensities of a group of waves after passing by an obstacle or through an aperture whose size is approximately the same as the wavelength of the waves
The aperture, then, starts to act like a new source of waves.
Subatomic particles which have dual behaviour ( particle-wave ), like electrons or photons, can also suffer diffraction.
THE BENDING OF WAVES
I am assuming you mean diffraction. A diffraction is a phenomenon that occurs when a wave passes through two slits and a pattern is observed a certain distance away from the slits. Because waves are unlike particles, when they go through a slit, they tend to spread out instead of going straight. When there are two slits and a wave is allowed to travel through it, it will "diffract" and display a pattern on an observatory wall.
This diffraction is one of the main factors that proved Einstein wrong when he said light behaves like a particle.
Waves have a tendency to spread as they propagate through a medium. As a result, when a wave encounters an obstacle, it spreads into the region behind the obstacle. This phenomenon is called diffraction. The amount of diffraction depends on the wavelength: The longer the wavelength, the greater is the spreading of the wave. Significant diffraction into the region behind the obstacle occurs only if the size of the obstacle is smaller than the wavelength. For example, a person sitting behind a pillar in an auditorium hears the performer because the long wavelength sound waves spread behind the pillar. But the view of the performance is obstructed because the wavelength of light is much smaller than the pillar, and, therefore, the light does not diffract into the region behind the pillar.
Objects that are smaller than the wavelength do not produce a significant reflection. This too is due to diffraction. The wave simply diffracts around the small obstacle, much as flowing water spreads around a small stick.
Both light waves and sound waves can be focused with curved reflectors and lenses. There is, however, a limit to the size of the focused spot. It can be shown that the diameter of the focused spot cannot be smaller than about λ/2. These properties of waves have important consequences in the process of hearing and seeing.
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.
How many classes of diffraction?
fresnel diffraction and fraunhoffer diffractions
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.
Can you give some viva voce question on laser diffraction?
Certainly! Here are a few viva voce questions on laser diffraction: What is the principle behind laser diffraction and how does it differ from traditional diffraction methods? Can you explain the significance of the diffraction pattern produced by a laser and how it relates to particle size analysis? How do factors such as wavelength and particle size influence the diffraction pattern observed in a laser diffraction experiment?
The bending of a wave around a barrier is called?
It is called diffraction.
Can you make a sentence with the word diffraction?
i couldn't make a sentence with diffraction! :)
Bending a wave around a barrier is called?
It is called 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.
Which term describes the bending of a wave around an object?
Diffraction is the term that describes the bending of a wave around an object. This phenomenon occurs when a wave encounters an obstacle or aperture and spreads out after passing through it.
What should be approximate size of slit to observe diffraction?
The width of the slit should be on the order of the wavelength of the light being used for diffraction in order to observe the diffraction pattern clearly. This is known as the single-slit diffraction condition. The size of the slit also affects the angular spread of the diffraction pattern.
