Diffraction patterns by elkement, collage with 1945 patent drawing

Diffraction patterns, again. But this time I tack them to an imaginary semi-circular screen. Screens grow bigger in radius with increasing wavelength - growing more reddish. If every wavelength would be diffracted in the same way, all peaks would lie on a radius of the circle. But as red is diffracted more, maxima move to … Continue reading Jellyfish of Diffraction

Newton’s Space Probes Investigate my Ribbons of Diffraction

I have been calculating diffraction patterns for visible light. Curves are displaced to turn the whole structure into a wavy ribbon built from colored wires or threads. I have turned these images into collages, adding Isaac Newton's drawings from Opticks (1704). The more I moved Newton's figures around, and the more I twisted the ribbons … Continue reading Newton’s Space Probes Investigate my Ribbons of Diffraction
