Diffraction of light is the bending of light waves as they pass through an opening or around an obstacle. It is a fundamental property of light and is responsible for the formation of patterns and shapes when light interacts with objects.
When light passes through a narrow slit, it spreads out and creates a diffraction pattern. The light waves interfere with each other, causing areas of constructive and destructive interference, resulting in a pattern of bright and dark bands.
The shape formed by diffraction of light around slits depends on the number and arrangement of the slits. Common shapes include single and multiple slits, circular and rectangular apertures, and diffraction gratings.
The diffraction pattern is affected by the wavelength of light, the size and shape of the slits, and the distance between the slits and the screen where the pattern is observed. The pattern can also be altered by changing the angle of the light source or the material of the slits.
Diffraction of light around slits has various practical applications, including in optical instruments such as cameras and telescopes, where it is used to enhance image resolution. It is also used in spectroscopy to analyze the composition of materials and in the production of holograms.
