SUMMARY
Robert Millikan conducted two pivotal experiments that significantly advanced the understanding of the electron's charge and the photoelectric effect. His oil drop experiment precisely measured the charge of the electron at 1.602 x 10^-19 coulombs. Additionally, Millikan's verification of Einstein's theoretical work on the photoelectric effect allowed for the measurement of Planck's constant, further solidifying the relationship between light and energy. These findings are foundational in the field of quantum physics.
