During diffraction, a wave bends around obstacles or spreads as it passes through an opening, causing it to spread out or interfere constructively or destructively. This results in the wave exhibiting patterns of light and dark fringes. Diffraction is a common phenomenon in everyday life and is used in various applications such as in optical instruments and in studying the properties of light.

What do waves do when diffraction happens?
When diffraction occurs, waves bend around obstacles or pass through small openings. This bending of waves allows them to spread out and change direction, creating patterns of interference and diffraction. Waves demonstrating diffraction exhibit properties like interference, spreading, and bending around obstacles, leading to phenomena such as wave interference patterns and the spreading of sound waves around a corner.
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.
When frequency increases what happens to diffraction?
When frequency increases, the diffraction of a wave becomes less pronounced. Higher frequencies have shorter wavelengths, making it easier for the wave to travel in a straight line and less likely to diffract around obstacles.
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.
As the wavelength decreases what happens to wave diffraction?
As wavelength decreases the wave diffraction will decrease, so the curve formed will be less noticeable. The sharpness of the diffraction will decrease that you can see will lessen.
Can sound wave diffract?
No. Diffraction is not a wave; it is something that HAPPENS to waves; to all sorts of waves.
What happens to a wave when it passes an edge or an opening?
It undergoes diffraction. Please see the related link for more information.

What are the differences between Fresnel and Fraunhofer diffraction?
The main difference lies in the distance from the diffracting object to the screen: Fresnel diffraction occurs when the source and the screen are at a large distance from the diffracting object, while Fraunhofer diffraction happens when the source and the screen are at an infinite distance from the object. Fresnel diffraction considers the wavefront curvature, while Fraunhofer diffraction assumes a flat wavefront. Fraunhofer diffraction leads to simpler mathematical expressions compared to Fresnel diffraction.
How many classes of diffraction?
fresnel diffraction and fraunhoffer diffractions

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 happens when a wave reaches the edge of an object?
When a wave reaches the edge of an object, it can either undergo reflection, transmission, or diffraction. Reflection occurs when the wave bounces off the object, transmission happens when the wave passes through the object, and diffraction occurs when the wave bends around the object. These interactions depend on the properties of the wave and the object it encounters.
Why are rays not diffracted by diffraction grating or thin film?
Rays are not diffracted by diffraction gratings or thin films because they interact with the surface on a macroscopic scale, not at the atomic level where diffraction occurs. Diffraction is a wave phenomenon that happens when light encounters an obstacle with dimensions on the order of its wavelength. Since rays don't exhibit wave properties, they do not diffract in the same way as waves.
