WebThe electromagnetic spectrum. Light, or electromagnetic radiation, comes in many forms. There are radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays and gamma rays, all of which form what is known as the 'electromagnetic spectrum'. The electromagnetic spectrum is subdivided into seven regions according to wavelength. WebEarly VHE gamma-ray astrophysics can be dated back to the early 80’s, when the Whipple experiment showed the existence of gamma rays at TeV energies [1]. Later on, a handful of sources were found by means of first generation telescopes such as AsGat, CAT or Celeste [2–4]. At the time, two different

What is visible light? Live Science

WebBut we humans are clever little animals and have managed to build instruments that can see the light we cannot. One of these is NASA's Fermi Gamma-ray Space Telescope, an observatory hanging out in low-Earth orbit, monitoring the sky for gamma rays, the highest-energy light in the Universe. WebJul 16, 2024 · Light with really short, high-energy waves can be gamma rays and X-rays (used in medicine). Long, low-energy waves of light fall in the radio and microwave part of the spectrum. Electromagnetic radiation includes waves that are bigger than the largest buildings and waves that are smaller than the tiniest particles known. sabbath prayer fiddler on the roof chords
