衍射 Diffraction(重定向自Diffraction Pattern)
![]() ![]() ![]() 绕射(英语:diffraction),又称衍射,是指波遇到障碍物时偏离原来直线传播的物理现象。 在古典物理学中,波在穿过狭缝、小孔或圆盘之类的障碍物后会发生不同程度的弯散传播。假设将一个障碍物置放在光源和观察屏之间,则会有光亮区域与阴晦区域出现于观察屏,而且这些区域的边界并不锐利,是一种明暗相间的复杂图样。这现象称为衍射,当波在其传播路径上遇到障碍物时,都有可能发生这种现象。除此之外,当光波穿过折射率不均匀的介质时,或当声波穿过声阻抗不均匀的介质时,也会发生类似的效应。在一定条件下,不仅水波、光波能够产生肉眼可见的衍射现象,其他类型的电磁波(例如X射线和无线电波等)也能够发生衍射。由于原子尺度的实际物体具有类似波的性质,它们也会表现出衍射现象,可以通过量子力学进行研究其性质。

Diffraction 衍射(重定向自Diffraction Pattern)
![]() ![]() ![]() Diffraction refers to various phenomena which occur when a wave encounters an obstacle or a slit. It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle. In classical physics, the diffraction phenomenon is described as the interference of waves according to the Huygens–Fresnel principle. These characteristic behaviors are exhibited when a wave encounters an obstacle or a slit that is comparable in size to its wavelength. Similar effects occur when a light wave travels through a medium with a varying refractive index, or when a sound wave travels through a medium with varying acoustic impedance. Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves. |
