How does the observation of discrete charge values in Millikan's experiment imply that charge is quantised?.
Model answer
What a good answer should say
- The observation of discrete charge values implies that charge cannot vary continuously but instead exists in fixed amounts, which supports the idea of quantisation.
- This leads to the conclusion that all electric charge is an integer multiple of the elementary charge.
Explanation
Why this works
This answer effectively links the observation of discrete values to the concept of quantisation, demonstrating a clear understanding of the implications of Millikan's findings. It tests the ability to connect experimental evidence to theoretical concepts.
