Robert Andrews Millikan/Place of birth
What was Robert Millikan’s childhood like?
Born in the small town of Morrison, Illinois, Millikan spent most of his childhood in a rural setting. His mother had been dean of women at a Michigan college before she relocated to Illinois and his father was a Congregational minister. At Maquoketa High School, Millikan was an excellent student.
What did Robert Millikan’s oil drop experiment prove?
Explanation: Millikan’s oil drop experiment proved that electric charge is quantized. At the time, there was still great debate whether electric charge was continuous or not. Millikan believed that there was a smallest unit of charge, and he set out to prove it.
Who did Millikan marry?
Greta Erwin Blanchard
Professor Millikan married Greta Erwin Blanchard in 1902; they had three sons: Clark Blanchard, Glenn Allen, and Max Franklin. He died on the 19th of December, 1953, in San Marino, California.
What did Robert Millikan get wrong?
One example: Millikan measured the charge on an electron by an experiment with falling oil drops, and got an answer which we now know not to be quite right. It’s a little bit off because he had the incorrect value for the viscosity of air.
Why did Millikan use oil instead of water?
Professor Millikan has made several innovations to improve the experiment. First, droplets of oil are used instead of water, to reduce the tendency of the droplets to evaporate while the experiment is being performed. was later traced to the fact that Millikan’s value of the viscosity of air had been a little low.
What are possible charges of oil droplets?
Looking at the charge data that Millikan gathered, you may have recognized that the charge of an oil droplet is always a multiple of a specific charge, 1.6×10−19C.
How did Millikan prove Einstein right?
The photoelectric effect is the emission of electrons when photons of light shine on a material and cause electrons to be displaced from the material’s atoms, resulting in an electric current on the material’s surface. Millikan had to change his mind when he proved the Photoelectric Theory and Einstein were correct.
What did the oil drop experiment prove?
Millikan’s oil drop experiment proved that electric charge is quantized. This was the big result of the oil drop experiment. That he could also determine the charge of the electron was a secondary benefit. This was probably one of the most significant experiments ever carried out.
What did oil drop experiment prove?
Where was Robert Andrews Millikan born and raised?
Robert Andrews Millikan was born on the 22nd of March, 1868, in Morrison, Ill. (U.S.A.), as the second son of the Reverend Silas Franklin Millikan and Mary Jane Andrews. His grandparents were of the Old New England stock which had come to America before 1750, and were pioneer settlers in the Middle West.
When did Robert Andrews Millikan win the Nobel Prize?
Robert Andrews Millikan was an eminent American experimental physicist who won the Nobel Prize for Physics in 1923 for his work on photoelectric effect. Check out this biography to know about his childhood, life, achievements, works & timeline.
How did Robert Millikan contribute to the atomic theory?
Robert Millikan, in full Robert Andrews Millikan, (born March 22, 1868, Morrison, Illinois, U.S.—died December 19, 1953, San Marino, California), American physicist honoured with the Nobel Prize for Physics in 1923 for his study of the elementary electronic charge and the photoelectric effect.
When did Robert Millikan become a full professor?
In 1896 he became an assistant at the University of Chicago, where he became a full professor in 1910. During his time in Chicago as an assistant professor, he wrote for high-school and college students several physics textbooks that entered widespread use.
