A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3-D displays, virtual reality and even self-driving vehicles. A two-dimensional array of the material has ...

Description: ELC-4481 optically transparent acrylic with a refractive index of 1.48 is an excellent material for use in fiber optics, lenses tacking and laser applications. Available in 300cps -- ...

In spooky season fashion, we are going to bring magic to this episode of Up and Atom. Well, science disguised as magic.

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
