BRYAN, Texas (KBTX) - In the midst of a foggy Thursday morning, an arc of white stretched above the horizon, catching the eye of many across the Brazos Valley. While similar to a rainbow, this ...

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 ...

We have again elucidated the mechanism of Bloch wave refraction in electron diffraction and shown that the phase term of the deviated diffraction peaks by high energy electrons will disappear in the ...

This disappearing spider trick is a simple Halloween science activity and a great refraction demonstration. Children can watch as a drawing of a spider disappears when water is poured into a glass ...

Diffraction refers to the bending of waves, such as light, when they encounter obstacles or pass through small openings. The size of the opening relative to the wavelength of light influences the ...

The first law of refraction states that the incident rays, refracted rays, and the normal to the interface at the point of incidence, all lie in the same plane. The ratio of the sine of the angle of ...

Internal conical refraction is a striking optical phenomenon which arises when a beam of light is incident along one of the optic axes of a slab of transparent biaxial crystal. The beam propagates as ...
