PPT-Discovery of X-rays X-rays were discovered on November 8, 1895, by Dr. Wilhelm Conrad

Accidental discovery First radiograph of Mrs Roentgens hand Roentgen received the first Nobel Prize presented for physics in 1901 Public viewed discovery as a novelty Radiographic imaging and therapy important to the medical sciences. He noted quickly that solid objects placed in the beam between the Crookes tube and the 64258uorescent screen serving as an image receptor attenuated or blocked the beam depending upon their density and structure Medical Applications of X Rays by O Roentgen and his Rays If serendipity is defined as the ability to spot valuable things when they are not specifically sought or pursued, it can be said that serendipitous events take place in the live B.Sc.
