The discovery of X-rays was made by a German physicist named Wilhelm Roentgen. In 1895 Roentgen discovered X-rays almost accidentally. While conducting several experiments in which he passed an electric current through a Crookes tube, Roentgen noticed that a nearby photo plate began to grow foggy.
When the flow of high-energy electrons which is very fast to attack the metal electrode (anode), the electrons slow down, and some of them penetrate into the metal. You can also get printing services of x-ray film bags via www.luxfordprint.com.au/radiology.
Sudden braking of electrons produces electromagnetic radiation with very short wavelengths: X-rays or Roentgen rays. This radiation is produced by electrons which penetrate into the metal and interact with metal atoms.
To find out why this happened, he put the black paper in the tube and then turned on the current. Nearby, a screen covered in barium began to glow. This led Roentgen to believe that an unknown ray produced in a tube passed through the paper to make this fluorescent substance emit light.
Here it is called X-rays because x is a scientific number for anything unknown. The main use of X-rays is in medicine. A common application is in the form of X-ray machines, which take photos of a patient's body.
If the arm or leg is broken for example, then this limb will be placed in front of the X-ray with a photographic film in the back. The x-ray is turned on briefly and enters the film.
