Optics 11 claims its underwater surveillance system can keep constant tabs on ships while remaining undetected.

Dark matter, although not visible, is believed to make up most of the total mass of the universe. One theory suggests that ...

In many ways, the exhibition, Science Through Artists’ Eyes, at Mumbai's Nehru Centre, achieved what it set out to ...

The principle of wave-particle duality is crucial in quantum physics, highlighting the dual nature of light and matter and ...

Huygens principle and the wave theory of light Thomas Young, Source: ... Huygens’ principle was introduced in 1678 to explain the reflection and refraction caused by light rays.

White light is made up of light of all different colors, or wavelengths. Since the index of refraction of the tape is different for each color of light, each color has its own unique pair of speeds as ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Optical lattices are like “egg cartons” made of light, where atoms are held in place by standing light waves. Dr. Lewis Ruks at NTT said: “These precisely arranged atomic crystals allow researchers to ...

Refraction occurs when light changes direction as it passes, e.g., ... Optical lattices are like "egg cartons" made of light, where atoms are held in place by standing light waves.
