Just as a ray of light is made up of many particles called photons, sound consists of particle-like chunks called phonons.

Radiation within the visible spectrum can appear black if it is low in power – more specifically, lower in power than its ...

The white light of the sun is made up of all the colours of the rainbow. And when it reaches the Earth, those individual colours are revealed. Photons from the sun rain down and enter water droplets.

Scientists have made a surprising discovery: they have managed to manipulate light particles in such a way that they can ...

The rich history of research involving photons is celebrated in a supplement ... preceded by others on such topics as spin, light microscopy, DNA technologies and cancer. Following the advice ...

Light, he noted, is made up of tiny packets called photons. While lasers may look orderly from the outside, their individual photons are anything but. "If you're detecting these photons ...

In 2PE you produce pairs of photons whose combined energy adds up to the electron-transition energy in the semiconductor. So by measuring the energy (wavelength) of one photon, you can deduce ...
