Light transmitted by means of neodymium Eyeglasses demonstrates unusually sharp absorption bands; the glass is Utilized in astronomical get the job done to make sharp bands by which spectral lines can be calibrated.[twelve] Another software is the generation of selective astronomical filters to lessen the impact of sunshine air pollution from sodium and fluorescent lighting when passing other colors, In particular darkish red hydrogen-alpha emission from nebulae.[sixty nine] Neodymium is additionally used to eliminate the green colour because of iron contaminants from glass.[70]
Manyetiklik durumunun sebebini atom ve moleküllerin manyetik momentlerine ve dış etkilerle cismin içindeki manyetik kuvvetin paralelleştirilmesine bağlar.
