Albert A. Michelson

Albert A. Michelson was an American physicist renowned for his precision measurements of optical phenomena. He is best known for the Michelson-Morley experiment, which aimed to detect the presence of a supposed medium for light travel, called 'ether.' This experiment helped pave the way for Einstein's theory of relativity. Michelson also contributed to spectroscopy, the study of how light interacts with matter, including analyzing spectral lines to understand atomic structures, which plays a crucial role in fields like geophysics and low-temperature physics. His work in physical optics further advanced our understanding of light's behavior.
