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.
The color of light depends on the wavelength. Infrared (IR) light has longer wavelengths than visible light. The electromagnetic spectrum comprises all wavelengths of light from the very short (gamma rays) to the very long (radio waves). Both visible and IR light are near the middle of the spectrum.
