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.
Radio Waves. Radio waves are a type of electromagnetic radiation. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications. Radio waves have wavelengths as short as a few millimeters (tenths of inches) and as long as hundreds of kilometers (hundreds of miles).
