Researchers at Rice University, Houston, Texas, have developed a new way to control light interactions using a specially ...

The only thing that differentiates one type of electromagnetic radiation from any other is the energy carried by its photons. There's lots to discover in the electromagnetic spectrum. Here's a ...

Electromagnetic radiation is carried by photons, massless particles that travel at the speed of light (300,000 kilometers per second in a vacuum). Every photon is characterized by wavelength (the ...

Research done by the Atacama Cosmology Telescope (ACT) project produced the clearest and most accurate images of the universe ...

Understanding the origin of heavy elements on the periodic table is one of the most challenging open problems in all of ...

or photons with sufficient energy that they can indirectly ionize atoms — gamma rays. Non-ionizing radiation, instead, makes molecules move using the produced electromagnetic field. Consider the ...

Researchers have long recognized that quantum communication systems would transmit quantum information more faithfully and be impervious to certain forms of error if ...

Quantum computing promises revolutionary advancements, capable of outperforming traditional technology in speed, accuracy, ...

Photoemission is a process during which electrons are ejected from a metal surface when exposed to electromagnetic radiation, (eg ultraviolet). If a clean, positively charged zinc plate is exposed ...

Inverse square law Irradiance of electromagnetic radiation from a point source of ... effect shows that light is made up of individual photons. Photoemissions will take place if photons have ...
