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.
Visible light is the visible part of the electromagnetic spectrum. The electromagnetic spectrum also contains things we cannot see. On the red side of the spectrum, there are radio waves, microwaves, and infrared. On the blue side, there are ultraviolet waves, x-rays and gamma rays. In physics (and optics), a light ray is an idealized model of light, which is drawn as a straight line.
