Diffraction | Definition, Examples, Types, & Facts | Britannica
2024年12月7日 · Diffraction, the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very small moving particles such as atoms, neutrons, and electrons, which show wavelike properties.
Diffraction - Wikipedia
Diffraction is the deviation of waves from straight-line propagation due to an obstacle or through an aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave.

2022年11月17日 · Diffraction is the bending or spreading of light waves around an obstacle. The obstacle can be an aperture or slit whose size is approximately the same as the wavelength of light. The amount of bending depends on the relative size of the opening compared to the wavelength of light.
Diffraction (Physics): Definition, Examples & Patterns
2020年12月28日 · Diffraction is the bending of waves around obstacles or corners. It happens to light waves, sound waves and water waves. This bending often causes waves to interfere with themselves, creating diffraction patterns. Diffraction also limits the resolution of anything using an aperture, like cameras.
17.1 Understanding Diffraction and Interference - Physics
The bending of a wave around the edges of an opening or an obstacle is called diffraction. Diffraction is a wave characteristic that occurs for all types of waves. If diffraction is observed for a phenomenon, it is evidence that the phenomenon is produced by waves.
What is diffraction in physics? - California Learning Resource …
2025年1月5日 · Introduction. In the world of physics, phenomena such as light, sound, and water waves can exhibit a fascinating property known as diffraction. Diffraction is the bending of these waves around an obstacle or through a narrow slit, resulting in the creation of new wave patterns and interference patterns. This fundamental concept is a fundamental aspect of physics, with …
4: Diffraction - Physics LibreTexts
Diffraction can send a wave around the edges of an opening or other obstacle. A single slit produces an interference pattern characterized by a broad central maximum with narrower and dimmer maxima to the sides.

4.S: Diffraction (Summary) - Physics LibreTexts
A diffraction grating consists of a large number of evenly spaced parallel slits that produce an interference pattern similar to but sharper than that of a double slit. Constructive interference occurs when \(\displaystyle d \sin θ=mλ\) for \(\displaystyle m=0,±1,±2,...\), where d is the distance between the slits, θθ is the angle ...

2022年7月20日 · Diffraction is the spreading out of waves when they pass an obstruction. Diffraction through a gap. This obstruction is typically a narrow gap (a slit, or aperture) Diffraction is usually represented by a wavefront as shown by the vertical lines in the diagrams above; The only property of a wave that changes when its diffracted is its amplitude
