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.
What are radio waves? Radio waves are part of a larger group of waves classified all together as electromagnetic radiation. This large group of waves is broken down into smaller groups based upon their frequencies and wavelengths. Two examples of electromagnetic radiation (other than radio waves) are: 1  Light -- which is the group of electromagnetic radiation you can see with your eyes.  X-rays -- which are a group from a higher frequency and they are what is used by doctors to see inside of you.
