Optics is a branch of physics that involves the properties of light and its interaction with matter. Reflection, refraction and diffraction are different ways light can behave based on the conditions ...

The dazzling spectacle unfolded in a matter of minutes, but its short-lived appearance has left an indelible mark on those lucky enough to witness it. Jenni Shaw, who was at her family-owned business ...

New diffraction phenomenon of acoustic waves. A novel asymmetric diffraction has been achieved using a nano-patterned array of ferromagnets. This demonstration arises from a unique interaction between ...

Researchers from the Institute for Materials Research at Tohoku University, in collaboration with the Japan Atomic Energy Agency and the RIKEN Center for Emergent Matter Science, have identified a new ...

Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...

A stunning natural spectacle recently graced the skies above Hong Kong, captivating onlookers with its surreal beauty. Rainbow-colored clouds in the shape of a “stairway to heaven” were spotted over ...

This novel finding regarding the nonreciprocal diffraction of acoustic waves could open doors for next-generation communication devices. A unique propagation phenomenon of acoustic waves has been ...
