Millikan undertook a decade-long experimental program to test einstein's theory by careful measurement of the photoelectric effect, and even devised techniques for scraping clean the metal surfaces inside the.
Einstein saw that planck's idea would explain some mysterious properties of experiments in which light shone on metal electrodes the photoelectric effect at the turn of the century, physicists who experimented with electricity had noticed something about the interaction of light, metals, and electric current.
Though millikan had been firmly against quantum theory, the results convinced him that einstein was right in millikan's photoelectric apparatus, monochromatic light was incident on each of the newly-cleaned metal plates in turn. This led to the two papers above, and contributed to nobel prizes for both einstein (the photoelectric effect is the only specific theory mentioned in his prize citation) and millikan there’s a bit of irony in this, because millikan didn’t much care for einstein’s theory.
It took the full development of quantum theory, which came a few years later, to put einstein’s photoelectric equation on a firm theoretical foundation up until that point it was, as millikan noted, an empirical relation, and millikan reported a firm experimental basis for that relation. Albert einstein and the theory of the photoelectric effect, a david darling home heinrich hertz became the first person to observe the photoelectric effect during his experiments that confirmed maxwell's it took a decade or so for the details of einstein's photoelectric theory to be thoroughly tested and verified in the lab. Robert millikan's primary contribution to atomic theory came as a result of his oil-drop experiment, which measured an electron's charge previously, jj thomson had suggested the hypothesis that an electron's mass was at least 1,000 times less than the mass of the tiniest atom millikan's. Millikan undertook a decade-long experimental program to test einstein's theory by careful measurement of the photoelectric effect, and even devised techniques for scraping clean the metal surfaces inside the vacuum tube needed for an.
