Chromatic aberration is an optical phenomenon that occurs when a lens fails to focus all colors of light at the same point, leading to a distortion in the image where colors are fringed or spread out. This effect arises due to the dispersion of light, which causes different wavelengths to bend by varying degrees as they pass through a lens. As a result, objects may appear blurry or have color fringes around their edges, impacting the clarity and quality of the image produced by optical devices such as cameras and telescopes.
congrats on reading the definition of Chromatic Aberration. now let's actually learn it.
