Research

On November 8, 1895, while working with cathode ray tubes, Conrad Röntgen discovered unknown radiation, which he called X-rays in his publication "Über eine neue Art von Strahlen" (On a new type of radiation) published shortly afterwards. He worked at the time as a professor of theoretical physics in Würzburg.  He found out that the rays penetrate materials differently depending on their density and produced the first X-ray images by directing the rays onto a photo plate.

He also worked on the quadratic electro-optic (QEO) effect, which is a change in the refractive index of a material in response to an applied electric field (Kerr effect), was able to prove that a magnetic effect occurs in a dielectric moved between electrically charged capacitor plates (X-ray current) and could verify the displacement current predicted by Maxwell's theory.
