koherenssileveyttä
Koherenssileveyttä refers to the spatial extent over which light maintains a predictable phase relationship. It is a fundamental concept in optics, particularly relevant in the study of interference and diffraction phenomena. When light is coherent, its wave crests and troughs align in a consistent manner across a certain region. If the light source is extended or the medium through which it travels is non-uniform, this coherence can be lost.
The koherenssileveyttä is often compared to temporal coherence, which describes the predictability of the phase of
The koherenssileveyttä is crucial for observing stable interference patterns. If the light illuminating two slits in
