Difraktsioon
Difraktsioon, also spelled diffraction, is a phenomenon that occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength. This results in the wave spreading out and bending around the edges of the obstacle or slit. The most common examples of diffraction are observed with light waves, but it also applies to other types of waves, such as sound and water waves.
The principle of diffraction was first described by Francesco Maria Grimaldi in the 17th century, and later
There are two main types of diffraction: Fresnel diffraction and Fraunhofer diffraction. Fresnel diffraction occurs when
Diffraction has numerous practical applications, including the design of optical instruments such as microscopes and telescopes,
