An EM wave by: Mary Kahler

The man who first discovered the x-ray Wilhelm Rontgen, a German scientist.

What are x-rays used for?

  • to see inside people/take pictures of bones, teeth, and ect. (an x-ray)
  • airport security checks (see inside luggage)
  • some cancer radiation
  • art historians use it to see if someone painted over another picture

EM wave: X-ray

Here is the whole EM spectrum, which includes x-rays. In the diagram it shows the frequency of a x-ray (listed to the side). The wavelength is 0.01 to 10 nano meters.

This video explains the different functions of an x-ray, the wavelength, frequency and much more.

New and improved X-ray

This new x-ray has the ability to not only see bones, but provides a detailed picture of bones, soft tissues, and vital organs, like the liver, without using harmful contrasting agents.

Who invented it and what is needed to operate it?

Scientist Luis Velasquez-Garica and his team discovered this at Massachusetts General Hospital and presented it at the 13th International Workshop on Micro and Nanotechnology for Power Generation and Energy Conversion Applications on

December 3, 2013 in London, England. For this new technology to operate, they found a way to produce clear x-ray beams from a variety of micro-sized point sources. Tiny chips would produce a beam of electrons that pass through a micro-structured plate that displays a beam of x-rays.

How will this impact our world?

This is a huge advance in x-ray technology. Doctors will no longer have to endanger their patients by giving them harmful contrasting agents to see soft tissues. This new machine is light weight and portable, allowing it to be easily accessed. Also it is electronic and will not take as much time to start it up as other thermal x-rays.
