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

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 important property of prisms in this article is their ability to redirect light through refraction and reflection. A collection of deck lights used to direct sunlight below deck in ships.

Experts say that rings around the moon can pop up from time to time, but have you ever seen one in Denver? Last night, at ...

This explains why a prism can disperse white light into different colours. The change in refraction is quite small and is only significant for some geometries. A ray of light is incident on the ...

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 ...

The Abilene Public Library invites you to join them for a magical science and art experience where kids will explore how light affects what we see! Through fun, hands-on experiments, participants ...
