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 ...

Negative refraction has been demonstrated with plasmonic materials 8,9 and with discrete nonlinear elements 10, but these approaches suffer from high losses and strong dispersion, which restricts ...

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 ...

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 ...

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 ...

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 ...

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 ...

CBSE Science Class 10 Chapter 9 Mind Map: Understanding science is a tough task that becomes a more tedious job if resources are limited. Chemistry, Physics, and Biology are the subjects of science.
