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]
