observatory, and the compton gamma ray observatory. examples of iacts are the high energy stereoscopic system (h.e.s.s.) and the magic telescope. besides studying electromagnetic radiation from distant objects, astrophysicists also look for such things as gravitational waves, neutrinos, and cosmic rays...

and transfer energy from one point to another, there is little or no permanent displacement of the particles of the medium. rather, the particles of the medium simply oscillate around fixed positions. electromagnetic radiation , which is constituted of radio waves (including microwaves ), infrared rays
, visible light, ultraviolet rays , x rays , and gamma rays . the various forms of electromagnetic radiation differ in their frequencies (and wavelengths), but they share other properties. they can propagate through a vacuum, traveling at a speed of approximately three hundred thousand kilometers/second...
