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 ...

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 ...
