A material that is capable of the “reverse diffraction” of light and that is inspired by butterfly wings has been made by researchers in the US. The structure combines features of the butterfly’s ...

The average 3D printer can’t recreate the tiny-scaled patterns of a diffraction grating directly; a typical diffraction grating may have up to 1000 lines per mm. Instead, ...

Vision is not perfect. When grating patterns are used as resolution targets, the highest spatial frequency resolvable by humans is about 50 cycles per degree of angle subtended at the observer's ...

Chocolate plus diffraction grating equals rainbow chocolate. Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating.

Figure 1: Numerical prediction of the interference fringe visibility as a function of the de Broglie wavelength: comparison of the TLI and the KDTLI for molecules of different complexity. To ...
