"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 ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

The unusual phenomenon of negative refraction of light is central to the realization of interesting optical devices such as superlenses and other novel schemes for guiding and imaging light. However, ...
