A research team led by SUTD has created nanoscale glass structures with near-perfect reflectance, overturning long-held ...

As a result, purple and magenta are known as "nonspectral" colors, because they don't really exist as actual electromagnetic ...

Moreover, the technique can obtain images outside the visible spectrum and even through tissues. The Kobe University development thus opens the door ... For centuries, lenses have worked the same ...

A pair of European satellites have created the first artificial solar eclipses through precise and fancy formation flying.

Swiss scientists have developed an ultra-thin lens that turns infrared light into visible light using lithium niobate and nanoscale patterns.

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can't see, has an even lower frequency ...

Visible light is a form of energy and part of the electromagnetic spectrum. Radio waves, microwaves, X-rays, and other kinds of light are also part of the electromagnetic spectrum, but visible ...
