Diffraction is a phenomenon that occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength. It involves the bending and spreading of waves as they pass around the edges of an obstacle or through an aperture.
In the context of light waves, diffraction can lead to patterns of constructive and destructive interference, producing patterns of light and dark regions. This is observable in various scenarios, such as when light passes through a narrow slit, around a small object, or when it interacts with a diffraction grating.
Diffraction is not limited to light; it also occurs with other types of waves, such as sound waves and water waves. The extent of diffraction depends on the wavelength of the wave and the size of the obstacle or opening. Generally, longer wavelengths experience more diffraction than shorter wavelengths.
Overall, diffraction is a key concept in wave physics and has applications in numerous fields, including optics, acoustics, and telecommunications.
