How did Millikan's oil-drop experiment contribute to the understanding of the electron?.
- A.It provided the first measurement of the electron's mass
- B.It confirmed the existence of the electron
- C.It measured the specific charge of the electron
- D.It demonstrated the wave nature of electrons
Model answer
What a good answer should say
- It measured the specific charge of the electron
Explanation
Why this works
Millikan's experiment allowed for the calculation of the specific charge of the electron by measuring the charge and mass of the oil droplets, linking them to the properties of electrons.
