X-ray rays can penetrate solid objects and are most commonly used in clinical radiography and crystallography to take internal photographs of objects or organs. X-rays, also known as X-rays, are a form of electromagnetic radiation. The web length of X-ray rays is shorter than Ultraviolet rays and longer than gamma rays. These X rays are produced from the X-ray tube, which is a hot cathode for a high velocity There is a vacuum tube using a high voltage to increase the speed of electrons coming out of it. High-velocity electrons collide with a metallic target called the anode, creating an X-ray. X-rays were discovered in 1895 by Wilhelm Conrad Röntgen. He was a German mechanical engineer and physicist. The first medical x-ray was taken by Wilhelm on the hand of his wife, Bertie Ludwing.
