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 ...

To achieve a very low refractive index, silica nanorods are deposited at an angle of precisely 45 degrees on top of a thin film of aluminum nitride. Credit: Rensselaer/Fred Schubert Schubert and his ...

Researchers from the Rensselaer Polytechnic Institute (RPI) have created a material that reflects virtually no light-- or absorbs it like a black hole. They've built this new material by stacking ...

Physicists in the US claim to have created the first thin optical film with a refractive index close to that of air. The film consists of an array of obliquely-deposited nanorods, which can ...

Brighter LEDs and better solar cells could be developed using the least reflective coating ever made. Researchers found that depositing an array of angled silicon-dioxide nanorods on a surface ...

It has been about two years since Yuri Milner announced his most audacious piece of science-focused philanthropy: Breakthrough Starshot, an attempt to send hardware to Alpha Centauri by mid-century.

Hongik University graduate Jihye Kang built her Purity furniture from acrylic and stainless steel as an exploration of the refractive effects that can be achieved with simple materials and shapes.
