Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

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 ...

"The colors of the spectrum, then, "are not Qualifications [alterations] of Light … (as 'tis generally believed), but Original and connate properties." When you purchase through links on our site, we ...
