Optical density wikipedia
WebMar 15, 2024 · Optical density is defined as the ability of an object to delay the transmission of light. It measures the speed of light through a substance which is affected by the wavelength of that particular light wave. Absorbance is the transfer of energy of wave. Absorption of light occurs more in an optically denser medium. WebA Fata Morgana (Italian: [ˈfaːta morˈɡaːna]) is a complex form of superior mirage visible in a narrow band right above the horizon. The term Fata Morgana is the Italian translation of "Morgan the Fairy" (Morgan le Fay of Arthurian legend). These mirages are often seen in the Italian Strait of Messina, and were described as fairy castles in the air or false land …
