Millikan's Oil Drop Experiment
Millikan's Oil Drop Experiment, conducted by American physicist Robert A. Millikan in 1909, stands as a seminal investigation in the realm of modern physics. This groundbreaking experiment meticulously measured the charge of the electron, a fundamental constant of nature. By observing tiny oil droplets suspended in an electric field, Millikan was able to calculate the charge on individual electrons, providing crucial insight into their properties. This experiment not only verified the quantized nature of electric charge but also solidified the value of the electron's charge, a pivotal achievement that continues to underpin our understanding of atomic and subatomic phenomena to this day.
