WebMichelson became a science instructor at the Naval Academy and in 1878 conducted an experiment to determine the speed of light. Well-received by men of science, the experiment launched Michelson into a career which eventually brought him a Nobel Prize and recognition as one of the pioneers of modern physics. [9] WebUpon his return to the United States, he determined the velocity of light to be 299,853 kilometres (186,329 miles) per second, a value that remained the best for a generation, until Michelson himself improved on it.

WebOct 19, 2024 · In 1881, Michelson performed for the first time the ether experiment that carries his name today. The result was negative, in that the expected difference between the speed of light in the direction of movement through the presumed ether, and its speed at right angles, was found not to exist. WebAn American physicist Albert A. Michelson determined the speed of light for which he received a Nobel Prize in 1907. Michelson’s method to determine the speed of light uses mirror having various faces rotating in very high speed. The simplified version of his experiment is shown in the following figure.
WebThese techniques gave the speed of light with an accuracy of about 1,000 miles per second. Albert Abraham Michelson . Albert Michelson was born in 1852 in Strzelno, Poland. His father Samuel was a Jewish merchant, not a very safe thing to be at the time. Purges of Jews were frequent in the neighboring towns and villages. His Annapolis experiment was refined, and in 1879, he measured the speed of light in air to be 299,864 ± 51 kilometres per second, and estimated the speed of light in a vacuum as 299,940 km/s, or 186,380 mi/s.

WebFirst, the Michelson–Morley experiment showed that the speed of light is independent of the orientation of the apparatus, establishing the relationship between longitudinal (β) and transverse (δ) lengths. WebAug 22, 2024 · Michelson was awarded the 1907 Nobel Prize in Physics for his field-defining work, including taking the first accurate measurement of the speed of light. His Nobel Prize was the first of 91 that since have been awarded to University of Chicago faculty members, alumni and researchers during their careers.
