What experiment did Henri Becquerel do?
What experiment did Henri Becquerel do?
When Henri Becquerel investigated the newly discovered X-rays in 1896, it led to studies of how uranium salts are affected by light. By accident, he discovered that uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate.
What did Edmond Becquerel study?
Edmond Becquerel is a French physicist who focused his studies on the solar spectrum, magnetism, electricity and optics. In 1839, he discovered the photovoltaic effect, the operating principle of the solar cell.
How did Antoine Becquerel contribute to the atomic theory?
In 1896, Becquerel discovered natural radioactivity. This caused Becquerel to wonder if there was any link between x-rays and naturally occurring phosphorescence. He conducted an experiment on uranium salts, which he inherited from his father. He hypothesized that the uranium would absorb light and reemit it as x-rays.
What contribution did Becquerel make to the study of nuclear chemistry?
Becquerel discovered radioactivity when experimenting with a fluorescent mineral that happened to contain uranium. Pierre and Marie Curie discovered that several elements exhibit this behavior and called the phenomenon radioactivity; they also discovered the radioactive elements polonium and radium.
How did Edmond Becquerel discovered the photovoltaic effect?
Edmond was interested in light and studied the phenomena of fluorescence and phosphorescence. In 1839 he placed two electrodes in an acidic solution and exposed one of the electrodes to light. He found that the device generated electricity. Becquerel had created the first photovoltaic cell.
How did Edmond Becquerel discover solar energy?
In 1839, French physicist Edmond Becquerel discovered the photovoltaic effect while experimenting with a cell made of metal electrodes in a conducting solution. He noted that the cell produced more electricity when it was exposed to light.
What is the best explanation of why it was important that Becquerel?
What is the best explanation of why it was important that Becquerel used a uranium salt in his experiments? Uranium atoms are radioisotopes. Which elements did the Curies discover?
Which describes the experiments of Becquerel and the Curies quizlet?
Q. Which describes the experiments of Becquerel and the Curies? Becquerel coined the term “radioactivity,” and the Curies showed that uranium requires x-rays to form radiation. Becquerel showed that uranium gave off radioactivity, and the Curies discovered other radioactive elements.
What is Henri Becquerel most famous for?
Henri Becquerel, in full Antoine-Henri Becquerel, (born December 15, 1852, Paris, France—died August 25, 1908, Le Croisic), French physicist who discovered radioactivity through his investigations of uranium and other substances. In 1903 he shared the Nobel Prize for Physics with Pierre and Marie Curie.
