A certain compound, potassium uranyl sulfate, glowed after being exposed to sunlight and Becquerel wondered if this glow, like the glow on the glass in Roentgen's X ray tube, contained X rays. A CERTAIN COMPOUND POTASSIUM URANEL SULPHATE GLOWED AFTER BEING EXPOSED TO SUNLIGHT AND BECHCARRAL WONDERED IF THIS GLOW LIKE THE GLOW ON THE GLASS IN RENTGEN'S X RAY TUBE CONTAINED X RAYS
 between these two sets of particles—atoms and electrons? In 1897, when the electron was discovered, a line of research that was to tie the two kinds of particles together had already begun. In 1895 the German physicist Wilhelm Konrad Roentgen (1845-1923) was working with cathode rays. He found that if he made the cathode rays strike the glass at the other end of the tube, a kind of radiation was produced. This radiation was capable of penetrating glass and other matter. Roentgen had no idea as to the nature of the radiation, and so called it “X rays”. This name, containing “X” for “unknown”, was retained even after physicists worked out the nature of X rays and found them to be light-like radiation made up of waves much shorter than those of ordinary light. [Illustration: _Antoine Henri Becquerel._] At once, physicists became fascinated with X rays and began searching for them everywhere. One of those involved in the search was the French physicist Antoine Henri Becquerel (1852-1908).
