X ray origin


X-rays are particle streams generated by the transition of electrons in atoms between two energy levels with very different energies. They are electromagnetic radiation with a wavelength between ultraviolet and gamma rays. Its wavelength is very short, between 0.01 and 100 angstroms. It was discovered in 1895 by the German physicist W.K. Roentgen, so it is also called Roentgen ray. Roentgen rays have high penetrating power and can penetrate many materials that are opaque to visible light, such as ink paper and wood. This kind of invisible rays can cause visible fluorescence of many solid materials, make photographic films sensitive and ionize the air. Those with a wavelength less than 0.1 angstroms are called super-hard X-rays, those with a wavelength in the range of 0.1 to 1 angstroms are called hard X-rays, and those with a wavelength in the range of 1 to 100 angstroms are called soft X-rays. X-rays were originally used for medical imaging diagnosis and X-ray crystallography. X-rays are also harmful rays such as ionizing radiation.


What is X-ray


X-ray is a kind of light, invisible light


X-rays are energy in the form of electron waves


The difference between X-ray and visible light is that each photon contains different energy


The energy contained in X-ray photons is 5000 times that of ordinary photons.


X-ray characteristics: due to its high photon energy, it can penetrate objects
