This kit demonstrates the X-ray diffraction of DNA by using patterns scaled up to diffract using laser pointers. The slide has 12 patterns to contrast between changing amplitude, period, and offset of ...

Specially made diffraction gratings use optical laser light to illustrate how wave-based material characterization techniques work, such as X-ray diffraction, electron diffraction, and neutron ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...
