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 ...

Rules for obtaining images formed by convex lens. In convex lens, the image is always formed at a point where at least two refracted light rays meet.. Rule 1: A ray of light which is originally ...

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.

The refraction of light at an interface is familiar as a rainbow or the 'bending' of a pencil in a glass of water. Here we show that particles can also be refracted and even totally internally ...

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.

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. Known as “spacetime wave packets,” these lasers follow different rules of refraction ...
