now we can understand Schroedinger’s equation where electron wave is shortening - this is the moment: k*pi/4, another use is anti reflection layer on the glasses or car front glass, look at the same color purple as anti reflexion layers: that’s the moment of dispersion ^^^ Look at precisely this moment at 45 deg: purple wave becomes green one, which is cca 550nm from 740nm: ^^^ and now imagine opposite process: Do you grasp it? Green layer on military binoculars interchanging towards purple waves? And bang you see it better because 740nm rips pupil better than 550nm energy? You see it now? https://www.facebook.com/informationaboutmaths/videos/665271606217636
