Modern technology uses many frequencies of electromagnetic radiation for communication, including radio waves, TV signals, microwaves and visible light. Now, a University of Utah study shows how ...

When scientists talk about radiation, they are referring to photons, which are massless particles. According to quantum mechanics, the energy of a photon is directly proportional to its frequency (i.e ...

Researchers at the National Institute of Standards and Technology (NIST) and collaborators have demonstrated a compact frequency-comb apparatus that rapidly measures the entire infrared band of light ...
