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 ...

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 ...

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 ...

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 ...

Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will reduce in speed as it travels through, causing it to change direction. Ray ...
