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). Visible light, for comparison, has wavelengths in the 400 to 700 nanometer range, about 5,000 times shorter than the shortest wavelength radio waves.
