Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

Graphene and negative refractive-index materials are two of the hottest topics in physics -- but one might not think they have much in common. Now, however, physicists in the UK and US have proposed ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

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 ...

Students use mirror equations to determine the position and type. Students use mirror equations to determine the position, type, and size of mirror images for curved mirrors mathematically. Optical ...

There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy that creates a breaking wave. But we'll look at swell angles and ...
