Yksireikädiffraktio
Yksireikädiffraktio, also known as single-slit diffraction, is an optical phenomenon that occurs when light waves pass through a narrow aperture, or slit, with a width comparable to the wavelength of the light. Instead of continuing in a straight line as predicted by geometrical optics, the light spreads out and deviates from its original path. This bending and spreading of light is a direct consequence of the wave nature of light.
When light encounters a single slit, each point on the slit acts as a source of secondary
The resulting diffraction pattern on a screen placed behind the slit typically consists of a central bright
