_] It did, but while investigating the problem in 1896, Becquerel found that the compound was giving off invisible penetrating X ray like radiation continually, whether it was exposed to sunlight or not. The radiation was detected because it would fog a photographic plate just as light would. IN EIGHTEEN NINETY SIX BECKCAREL FOUND THAT THE COMPOUND WAS GIVING OFF INVISIBLE PENETRATING X RAY LIKE RADIATION CONTINUALLY WHETHER IT WAS EXPOSED TO SUNLIGHT OR NOT THE RADIATION WAS DETECTED BECAUSE IT WOULD FOG A PHOTOGRAPHIC PLATE JUST AS LIGHT WOOD
e 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). 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.
