Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. When white light passes through a coloured filter, all colours are absorbed except for the colour ...

Waves close wavesVibrations that transfer energy from place to place without the transference of matter. – including light – can be reflected at the boundary between two different materials.

Real physical waves, such as light beams, spread, diffract, scatter and interfere in complex and chaotic ... Our recent work in this area spans a diverse range of topics, including superoscillations ...

Researchers manipulated water waves to move ping pong balls with a level of precision that seems straight out of a sci-fi movie.

Imagine a world where your phone stays cool no matter how long you use it, and it's also equipped with tiny sensors that can ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Atoms, electrons, light waves, none of these things followed the normal rules. As physicists like Niels Bohr and Albert Einstein began to study particles, they discovered new physics laws that ...
