Soon after Wilhelm Conrad Röntgen took an x-ray of his wife’s hand. The wedding ring appeared on the picture and had completely blocked out the x-rays. This is the reason that they appear black. This new form of radiation created a great interest in both the scientific field and public sector.

What are x-rays and what are they used for?

X-rays are a form of electromagnetic radiation. X-rays have high energy and short wavelength and are able to pass through tissu

X-rays have very small wavelengths, which is the distance in the line of advancement of a wave from any point to the next corresponding point, the high energy is a consequence which seems to act more as a particle than a wave. X-rays are part of the electromagnet spectrum and they are related to radio waves, infrared waves, visible light rays, ultraviolet rays, and gamma rays. X-rays belong to the wave lengths between ultra violet and gamma rays. All electromagnetic waves travel through space at the same speed, approximately 186, 000 miles per second.

A special type of photographic film is used to record X-ray pictures. The X-rays are converted into light and the more energy that has reached the recording system, the darker that region of the film will be. This is why the bones on an X-ray image appear whiter, where less energy passes through, than the lungs, where more energy passes through).

The shorter the wavelength the greater the energy of the ray and the greater the energy the more penetrating the ray will be. Therefore x-rays can be classified as “hard” or “soft”. Hard rays have shorter wavelengths than soft rays therefore are more pene
