How does Millikan's oil-drop experiment provide evidence for the quantization of charge?.
Model answer
What a good answer should say
- Millikan's oil-drop experiment shows that the charges measured on the oil droplets are always multiples of a fundamental value, which corresponds to the charge of a single electron.
- This indicates that charge is quantized, as it cannot take on arbitrary values.
Explanation
Why this works
This answer effectively connects the experimental results to the concept of charge quantization, demonstrating a clear understanding of the implications of Millikan's work. The question assesses the student's ability to apply knowledge of the experiment to a broader concept in physics.
