Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have many ...

The film explores the properties of light, including reflection and refraction, through various experiments. It demonstrates how light travels in straight lines, how mirrors can reflect images, and ...

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 led ...

The questions in this quiz are suitable for GCSE physics students who are studying reflection of waves and refraction of waves. If you struggled with the quiz, don't panic - we've got you! You can ...

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. We discovered that the most primitive form of photography was the camera obscura, which ...

The formation of a rainbow requires the observer to be between the sun and falling rain, with the rain in front and the sun behind. Sunlight passes from behind the observer, refracts as it enters each ...

The new design ' Liquid Glass ' was announced at the keynote speech of the annual developer conference ' WWDC25 ' held by Apple from 2:00 on June 10, 2025. Liquid Glass will be used in all Apple ...
