What is the difference between X-rays and Visible Light? â¢ X rays are high energy electromagnetic waves, but visible light is medium energy electromagnetic waves. â¢ The visible spectrum is very narrow compared to the X-ray spectrum. â¢ X rays can penetrate the human body but visible light is not capable of doing that.
All kinds of radio waves are a form of electromagnetic radiation, which also includes visible and ultraviolet light, X-rays and gamma rays. Each type of electromagnetic radiation has a characteristic range of wavelengths determined by the speed of light, 186,000 miles per second. Radio frequencies range from about 100 kHz to 300 GHz and have corresponding wavelengths of 3,000 meters to 1 millimeter. Satellite communications range from about 20 meters to the shortest radio wavelengths.
