For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the ...

Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic arrays instead of engineered metamaterials. This breakthrough has enormous ...

The prism bends different colours of light at different angles. This is called refraction. This can happen in raindrops too. When sunlight enters a raindrop the different colours of light are ...

A material coating, whose light refraction properties can be precisely ... Walden et al, Two-Color Spatially Resolved Tuning of Polymer-Coated Metasurfaces, ACS Nano (2024). DOI: 10.1021/acsnano.

An example of refraction is a pencil in a glass of water. The pencil appears to bend. Reflection is when the light bounces off an object and stays the same color. Sun dogs and halos are almost ...
