difraktsioonilähenemine
Diffraktsioonilähenemine is a computational method used in physics and engineering to approximate the diffraction pattern of waves. It is particularly useful for analyzing diffraction phenomena when the wavelength of the wave is small compared to the size of the diffracting object or aperture. The core idea behind the diffraction approximation is to simplify the wave equation under certain conditions, making the problem more tractable.
This approximation is often employed in scenarios involving diffraction gratings, apertures, and scattering from small particles.
The validity of the diffraction approximation depends on the specific physical situation. It generally holds well
