SUMMARY
Millikan's experiment, specifically the oil drop experiment, demonstrates the observation of vibrating oil droplets due to Brownian motion. This phenomenon occurs as the droplets are subjected to random collisions with molecules in the surrounding air, causing them to vibrate. The original experiment involved extensive measurements to minimize the impact of these fluctuations, showcasing Millikan's dedication to precision in scientific research. Understanding this effect is crucial for interpreting the results of the oil drop experiment accurately.
