Becquerel's Experiment's

Becquerel first discovered radioactivity on March 1, 1896. The experiments that Becquerel did were when he was investigating on X-Rays which led to him studying how uranium salts are affected by light. By accident he discovered that the salts emit a penetrating radiation that can be registered on a photonic plate. Studying more he discovered that radiation was new and not X-Ray radiation, he discovered, Radioactivity.
