Albert A. Michelson - Wikipedia
Albert Abraham Michelson (surname pronunciation anglicized as Michael-son; December 19, 1852 – May 9, 1931) was a German-born American physicist known for his work on measuring the speed of light and especially for the Michelson–Morley experiment.

Dec 15, 2024 · A.A. Michelson was a German-born American physicist who established the speed of light as a fundamental constant and pursued other spectroscopic and metrological investigations. He received the 1907 Nobel Prize for Physics.
Albert A. Michelson – Biographical - NobelPrize.org
He performed early measurements of the velocity of light with amazing delicacy and in 1881 he invented his interferometer for the purpose of discovering the effect of the Earth’s motion on the observed velocity.

Dec 19, 2018 · The period after 1927 marked the beginning of new measurements of the speed of light with new optoelectronic sensors, all of which were significantly below Michelson’s 1926 level. Michelson was looking for another measurement method, but this time in an evacuated tube, to avoid difficulties in image interpretation due to atmospheric effects.

Oct 18, 2019 · He performed early measurements of the speed of light with unprecedented accuracy and won the Nobel Prize in Physics for his work, becoming the first American to do so. Using an Interferometer, an instrument he designed, Michelson proved that light travels at a constant speed in all inertial systems of reference and enabled distances to be ...
Michelson-Morley Experiment: Explanation, Apparatus & Result
May 9, 2020 · Michelson and Morley measured the speed of light by observing the interference fringes produced by the two beams. They expected that the light would travel faster along an arm if oriented in the same direction as the ether was moving, and …
Mount Wilson Observatory | VT Michelson Site
By measuring the tiny change in angle of the mirror during a round trip of a burst of light, taking only two ten-thousandths of a second, the speed of light was measured.This elegant experiment, devised and carried out during 1924-26 by Albert A. Michelson, America’s first Nobel Prize winner in a science field, provided the first modern and ...
Experimental Determination of the Velocity of Light, by Albert A. Michelson
These experiments, made with very crude apparatus and under great difficulties, gave the following table of results for the velocity of light in miles per second: or 300140 kilometers per second. In the following July the sum of $2,000 was placed at my disposal by a private gentleman for carrying out these experiments on a large scale.
