Millikan's Experiment, also known as the Oil Drop Experiment, was conducted by physicist Robert Millikan in 1909 to determine the fundamental unit of electrical charge, now known as the electron's charge.
The experiment involved observing the motion of tiny oil droplets suspended in an electrically charged chamber. The droplets were charged by X-rays, and then their motion was measured and analyzed to determine the charge of each droplet.
Millikan's experiment successfully measured the charge of each droplet and found that they were all multiples of a single, fundamental unit of charge. This fundamental unit was later identified as the charge of a single electron.
Millikan's Experiment provided the first direct measurement of the charge of an electron, which was a major contribution to our understanding of atomic and subatomic particles. It also helped to solidify the theory of quantized charge and paved the way for further advancements in the field of particle physics.
Millikan's Experiment remains an important milestone in the history of physics and is still referenced and studied in modern scientific research. The principles and techniques used in the experiment are also applied in various fields such as aerosol science, nanotechnology, and surface chemistry.
