Becquerel remained interested in problems of magneto-optics for years, and he returned to the field with renewed enthusiasm in 1897 after Dutch physicist Pieter Zeeman's discovery of the Zeeman effect -whereby spectral lines exposed to strong magnetic fields split -provided new impetus for research. He found that gases (except for oxygen ) also have the ability to rotate a beam of polarized light. He published this result in his first scientific paper in 1875, though he later discovered that his initial results were incorrect in some respects.Īlthough the Faraday effect had been observed in solids and liquids, Becquerel attempted to replicate the Faraday effect in gases. Becquerel developed a formula to explain the relationship between this rotation and the refraction the beam of light undergoes when it passes through a substance. ![]() Faraday had discovered in 1845 that a plane-polarized beam of light (one that contains light waves that vibrate to a specific pattern) experiences a rotation of planes when it passes through a magnetic field this phenomenon was called the Faraday effect. Antoine-Henri's father, Alexandre-Edmond Becquerel, was also scientist, and his research included studies on photography, heat, the conductivity of hot gases, and luminescence.ĭuring his years at the Ecole des Ponts et Chauss ées, Becquerel became particularly interested in English physicist Michael Faraday's research on the effects of magnetism on light. He made important contributions to the study of electrochemistry, meteorology, and agriculture. His grandfather, Antoine-C ésar Becquerel, had fought at the Battle of Waterloo in 1815 and later earned a considerable reputation as a physicist. Becquerel's other notable research included the effects of magnetism on light and the properties of luminescence.īecquerel was born in Paris on December 15, 1852. For these discoveries Becquerel shared the 1903 Nobel Prize in physics with Marie and Pierre Curie. His later research on radioactive materials found that at least some of the radiation produced by unstable materials consisted of electrons. Becquerel's student, Marie Curie, later named this phenomenon radioactivity. X rays were discovered in 1895 by the German physicist Wilhelm Conrad R öntgen, and in one of the most serendipitous events in science history, Becquerel discovered that the uranium he was studying gave off radiation similar to x rays. He died in Le Croisic, France on August 25, 1908.Antoine- Henri Becquerel's landmark research on x rays and his discovery of radiation laid the foundation for many scientific advances of the early twentieth century. In 1903, Becquerel received the Nobel Prize in Physics for his research on radioactivity along with Pierre and Marie Curie. Becquerel had, in fact, discovered radioactivity. While Becquerel initially believed the rays he was observing were similar to x-rays, further experiments should that unlike x-rays, the magnetic and electric fields of these rays could be deflected. He found that even without contact to sunlight, the uranium was emitting radiation. However, on a cloudy day in March, Becquerel decided to develop photographic plates of uranium that had not been exposed to sunlight. He developed the plates and observed that the uranium had, in fact, emitting radiation similar to x-rays. He put the uranium on photographic plates. He hypothesized that the uranium would absorb light and reemit it as x-rays. He conducted an experiment on uranium salts, which he inherited from his father. This caused Becquerel to wonder if there was any link between x-rays and naturally occurring phosphorescence. A type of phosphorescence had been present in vacuum tubes during Röntgen’s experiment. ![]() Earlier that year, German physicist, Wilhelm Röntgen discovered x-rays. In 1896, Becquerel discovered natural radioactivity. In 1895, he was appointed Professor at École Polytechnique. He later became Professor of Applied Physics in the Department of Natural History at the Paris Museum, a post his father had held previously. Becquerel received a Doctor of Science degree in 1888. In 1894, he was appointed chief engineer of the department. After a couple of years, he began working for the French government’s Department of Roads and Bridges. He began his studies in 1872 at École Polytechnique just south of Paris. He was the son of a professor of applied physics, Alexander Becquerel. Becquerel was born in Paris, France on December 15, 1852. Antoine Henri Becquerel (1852-1908) was a French physicist and winner of the 1903 Nobel Prize in Physics. ![]()
