Brett Smith for redOrbit.com - Your Universe Online Having been commercially manufactured since the 1960s, semiconductors are the backbone of modern electronics. However, these materials are slowly being replaced by superconductors – particularly in the field of astrophysics. Superconductivity is essentially a quantum phenomenon that happens when certain materials are cooled to near absolute zero. This cooling eliminates electrical resistance and magnetic fields, allowing for the...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...

Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
