Electromagnetic Radiation Explore the physics underlying X-rays, light, and other kinds of electromagnetic radiation. www. colorado. edu/physics/2000/xray/index. html www. colorado. edu/physics/2000/xray/index. html. Alternate Name(s): General Radiography; Plain films. X-rays are a form of electromagnetic radiation, just like visible light. In a health care setting, x-rays are emitted by a machine as individual "particles" (photons) that pass through the body and then get detected by a sensitive film. www. nlm. nih. gov/medlineplus/ency/article/003337. htm#Def. www. nlm. nih. gov/medlineplus/ency/article/003337. htm#Definition. var wikiImage = new Image(); wikiImage. onload = function() &ob;if(this. height An X-ray (or Röntgen ray) is a form of electromagnetic radiation with a wavelength in the range of 10 to 0. 01 nanometers, corresponding to frequencies in the range 30 PHz to 30 EHz.

For example, mammograms use X-rays to look for tumors or suspicious areas in the breasts. www. nlm. nih. gov/medlineplus/xrays. html www. nlm. nih. gov/medlineplus/xrays. html. As the wavelengths of light decrease, they increase in energy. X-rays have smaller wavelengths and therefore higher energy than ultraviolet waves. X-rays were first observed and documented in 1895 by Wilhelm Conrad Roentgen, a German scientist who found them quite by accident when experimenting with vacuum tubes. science. hq. nasa. gov/kids/imagers/ems/xrays. html science. hq. nasa. gov/kids/imagers/ems/xrays. html. X-rays were first discovered in 1895 when, during experiments with electric currents passed through a vacuum tube, Wilhelm Conrad Röntgen noted that a nearby fluorescent screen glowed when the current was being passed. When the current was switched off the screen stopped glowing.
