Eyewitnesses filmed a spectacular light effect over the Chinese capital last week. There appeared to be three 'suns' in the ...

The illusion taps into the brain’s tendency to compare different parts of an image, especially when different colours are ...

An international team of researchers, led by physicists from the University of Bath, has recently uncovered a novel optical ...

Some optical phenomena depend on the quantum nature of light and the interaction of light with matter. Geometric optics and physical optics are models that describe phenomena while ignoring properties ...

THE arc through the sun described by Mr. C. J. P. Cave 1 can only, I fear, be identified with the horizontal circle and not with some rare tilted arc. Its identity is clear from the fact that it ...

In a groundbreaking study, researchers have developed optical spring tracking to enhance signal clarity in gravitational-wave ...

The same phenomenon can occur with the sun as the light source ... that’s because the sun’s light is cast upward, creating ...

Optical activity refers to the phenomenon where light's polarization rotates as it passes through specific materials. This effect arises fundamentally from the 'nonlocality' of optically active ...

Superradiance in optical cavities involves atoms emitting light collectively when interacting with cavity photons, a ...
