How is the wavelength of gamma rays determined?

Let us work out the wavelength of a typical gammaray of 1 MeV. Energy of the gamma ray = 1 MeV. Let us see how much is 1 eV (electron Volt) an unit of energy in terms of erg. Now 1 eV = (charge of an electron in esu)×(potential drop in esu) = 4. read more

Gamma-rays can be used to treat cancer, and gamma-ray bursts are studied by astronomers. Electromagnetic (EM) radiation is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic spectrum. read more

Terminology varies between scientific disciplines, and in astrophysics gamma rays are conventionally defined as having photon energies above 100 keV and are the subject of gamma ray astronomy, while radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy. read more

Gamma rays typically have frequencies above 10 exahertz (or >1019 Hz), and therefore have energies above 100 keV and wavelengths less than 10 picometers (10−11 m), which is less than the diameter of an atom. However, this is not a strict definition, but rather only a rule-of-thumb description for natural processes. read more
