The X-rays ionized the air, causing electrons to attach to the falling oil droplets. To create the droplets, an atomizer was used to introduce oil into the chamber, where they became charged through friction or exposure to X-rays.
A Student Guide to Performing and Understanding the Millikan Oil Drop Experiment
The Millikan oil drop experiment was not just a clever demonstration of electric forces; it was a meticulous operation that finally allowed scientists to isolate the fundamental charge of the electron. This allowed them to calculate the mass of the droplet using Stokes' law, which describes the drag force on a sphere moving through a viscous fluid.
This value, incredibly close to the modern accepted value of 1. A microscope allowed the team to peer into this chamber and observe the droplets clearly.
