A mirror image is the result of light rays bounding off a reflective surface. Reflection and refraction are the two main aspects of geometric optics.

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.

Learn about the law of reflection through ray diagrams and plane mirrors, and the key facts of refraction with a practical experiment using ray tracing.

Everything CCEA students need to know about the reflection and refraction of light for GCSE Physics.

There has been a surprise discovery of ‘significant’ refraction of gamma rays which opens the door to nuclear photonics and the use of high energetic light beams to investigate the atomic ...

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

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 ...

Refraction is the bending of light when it goes from one medium to another so, when a ray of light passes through a prism it deviates.

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 ...

This requires refraction (bending) of light rays to form a sharp image on your retina. This refraction is performed by the cornea and lens.

In this extract from the new book Beautiful Experiments: An Illustrated History of Experimental Science, science writer Philip Ball explains how Isaac Newton transformed our understanding of light.
