It discusses the role of wave interference in producing holograms, using sound and light waves as examples. The film demonstrates the use of lasers to capture and reconstruct images through ...

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...

Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called ...

A team of researchers in Switzerland, Germany and the US has observed clear evidence of quantum mechanical interference ...

As only waves demonstrate interference, this confirmed that light ... demonstration of how to measure the wavelength of a laser beam, also called the double slit experiment.
