Are radio waves completely different physical objects than gamma-rays? They are produced in different processes and are detected in different ways, but they are not fundamentally different. Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be ...
Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency. Frequency is measured in cycles per second, or Hertz. Wavelength is measured in meters. Energy is measured in electron volts. Each of these three quantities for describing EM radiation are related to each other in a precise mathematical way. But why have three ...
Most electromagnetic radiation from space is unable to reach the surface of the Earth. Radio frequencies, visible light and some ultraviolet light makes it to sea level. Astronomers can observe some infrared wavelengths by putting telescopes on mountain tops. Balloon experiments can reach 35 km above the surface and can operate for months. Rocket f...
Nov 3, 2024 · A gamma ray is electromagnetic radiation of the shortest wavelength and highest energy. Gamma-ray radiation has wavelengths generally smaller than a few tenths of an angstrom (10 −10 meter), and gamma-ray photons have energies greater than tens of thousands of electron volts.
- Gamma rays are produced during the disintegration of radioactive atomic nuclei and the decay of certain subatomic particles. Gamma rays are also pr...
- The term gamma ray was coined by British physicist Ernest Rutherford in 1903, following early studies of the emissions of radioactive nuclei.
- Medical applications of gamma rays include the imaging technique of positron emission tomography (PET) and radiation therapies to treat cancerous t...
Jul 18, 2024 · Radio waves and microwaves are the longest wavelengths and lowest energies of light. With this in mind, they are used to peer inside dense interstellar clouds and track the motion of cold, dark...
Scientists use satellites to observe x-ray radiation coming from galaxies and stars like our Sun. Gamma Rays: Gamma rays have the most energy of any wave in the electromagnetic spectrum and are produced by the hottest and most energetic objects in the universe.
Oct 24, 2024 · Electromagnetic radiation - Spectrum, Wavelengths, Properties: The brief account of familiar phenomena given above surveyed electromagnetic radiation from low frequencies of ν (radio waves) to exceedingly high values of ν (gamma rays).

Thus, higher frequency photons have more energy. For example, a 10 20 Hz gamma ray photon has 10 19 times the energy of a 10 1 Hz extremely low frequency radio wave photon. The effects of EMR upon chemical compounds and biological organisms depend both upon the radiation's power and its frequency.
