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 ...

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 ...

Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...

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 ...

Researchers are making progress toward a “perfect lens” that will be able to resolve an organelle assembling a protein or a virus attacking a cell. From ribosomes assembling proteins to viruses ...
