X-ray is an electromagnetic wave with a wavelength of about 10-10 meters, which is beyond the range of wavelength visible to the human eye. It is often used in hospitals to produce images of patient's internal organs and bones on a photographic plate.
- X-rays were discovered in 1895 by Wilhelm Conrad Röntgen, who received the first Nobel Prize in Physics in 1901. [1]

- X-rays are part of the electromagnetic spectrum, which includes radio waves, microwaves, and visible light. They have an extremely short wavelength or high frequency, thus giving them high energy. X-rays can penetrate most materials except lead shielding. They are used in medicine and industry to examine structural problems. When they were discovered, the "X" stood for "unknown," because they were so mysterious. The name has been used ever since. [2]
