WHAT IS MILLIKANS OIL DROP EXPERIMENT ?

On March 22, 1868, famous American Physicist Sir Robert Andrews Millikan was born.
In the year 1910, Robert Millikan has conducted famous Oil Drop Experiment. Before the experiment, existence of sub atomic particles in an atom weren’t accepted universally.
Robert Millikan’s could successfully determine the charge & mass of an electron present in an atom. Electron had charge 1.602 X 10-19 Coulombs & mass 9.11 x 10 -31Kg.
In 1923, Physicist received Nobel Prize for charge calculation of electron and his contribution to Photo-electric Effect.Millikan's Oil Drop Experiment is used for determining the charge and mass of an Electron
Millikan’s Oil Drop Experiment Audiovisual displays experiment conducted by Robert Millikan, visualizes oil drop in ball form, on x ray exposure electrons released from air , clings to oil droplet making it negative charge was provided with in-depth animation bringing conceptual clarity.
Note :
In the Audiovisual Millikan's oil experiment, on exposure of X rays, it has been visualized as ionization of oil drop. But in reality on exposure of X Rays, the air inside the chamber gets ionized & there by liberates electrons. These emitted electrons get attached to the oil drop and thus makes it negatively charged.
