in general, the x-rays are produced when electrons with high energy ударяются on any object. the rays are not the electrons themselves, but, rather, of the electromagnetic waves. therefore, in the way they look similar to the visible spectrum (i.e. light waves), but their wave length is much shorter. the most famous use of the x-ray is, of course, their use in the medical diagnosis and treatment of teeth. another application of the radiotherapy in which rays destroy malignant tumors or stop their growth.the x-ray beams have wide industrial application, for example, can be used to measure the density of certain materials or for the detection of internal defects. these are useful in many areas of science, from biology to astronomy.as a result of further research, the scientist found that the tube is of unknown radiation called them subsequently, x rays. x-ray experiments showed that x - rays are in collision with the barrier inside the cathode cathode ray tube (bremsstrahlung accelerated electrons). the scientist made up of special construction is антикатод was flat, so as to ensure the flow of x - rays. the tube (she would later be named x-ray) for several weeks, examined and described the basic properties of previously unknown radiation which has received the name of x-ray.
