German scientist discovers X-rays. On this day in 1895, physicist Wilhelm Conrad Rontgen (1845-1923) becomes the first person to observe X-rays, a significant scientific advancement that would ultimately benefit a variety of fields, most of all medicine, by making the invisible visible.
X-rays are a form of electromagnetic energy just light-rays and micro-waves are. X-rays have more energy than light-rays so they can penetrate and travel through materials that light-rays cannot. Film is sensitive to x-rays in the same way that it is to light-rays, so X-rays can be used produce images. X-rays that are sent through an object can produce an image on a piece of film placed on the opposite side of the object.
