Refraction of light When the light rays either bend or change their direction while passing from one medium to another it is called refraction of light.

Sunlight, moonlight, torchlight... They all work the same. Let's talk about light!

Learn about refraction, ray diagrams and how convex lenses bend light rays with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

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 ...

Maxwell's Equations tell us a lot about electromagnetic interactions and physics. In the mid-1800s, Scottish physicist James Maxwell thought something interesting was going on with electric fields ...

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. In this Snapshot we will discuss the difference between reflection and refraction, how ...

In such systems, light interacts with atoms in a controlled and precise manner, without the absorption losses that typically convert light into heat. These unique properties make atomic media a ...

Two laser pointers were attached to the blackboard, and an elderly person demonstrated the effects of concave and convex lenses on light using both reading glasses and bifocals. This footage was ...

Angle of refraction r = angle between the refracted ray and the normal. Remember: Angles of incidence and refraction are always measured between the normal and the ray of light.

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has ...

One ray of light becomes parallel to the principal axis of the lens and thus, passes through another focus after refraction through the lens. Another ray of light passes through the optical centre ...
