Scientists at Heriot‑Watt University have demonstrated in a world-first, that light can be used to control every aspect of how electromagnetic waves oscillate, opening new technological frontiers.

A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

Invisible infrared waves are emitted by IR LEDs and detected by photodiodes to enable devices like remotes, automatic ...

Physics fans are a lot like surfers. Both think waves are really fun. For surfers, it’s all about having a good time. For physicists, it’s about understanding some of nature’s most important physical ...

For the first time, scientists have directly detected gravitational waves — ripples in space-time — in addition to light from the spectacular collision of two neutron stars. This marks the first time ...

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...
