Application of X-Ray in Industry

X-Rays were discovered by W. K. Rontgen in 1895. He was the Professor of Physics in the University of Wurzberg in Baveria. He was working with a highly evacuated Cathode ray tube. He found that a barium platino cyanide plate placed accidentally in the neighborhood of the tube began to glow with fluorescent light. He concluded that there must then be some new radiation emanating from the sides of the glass tube where the Cathode rays impinged. This new radiation, he named X-rays or unknown rays. The most noteworthy thing about the X-rays is their great penetration power. Things opaque to visible light are quite transparent to them.
