Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to ...

The Crab Pulsar, a remnant of a supernova whose burst was visible from Earth in 1054, emits a mysterious radio signal known ...

Young's experiment showed interference of light. As only waves demonstrate interference, this confirmed that light was a wave motion not a stream of particles. Watch this video for a practical ...

A recent paper explores the multiplexing of infinite functionalities using a single metasurface, leveraging coherent wave ...
