How did the observations from cathode ray experiments contribute to the discovery of the electron?.
Model answer
What a good answer should say
- Observations showed that cathode rays could be deflected by electric and magnetic fields, indicating they are charged particles.
- This led to the implication that these particles must have mass and charge, culminating in the identification of the electron as a fundamental particle.
Explanation
Why this works
This answer effectively summarizes the link between experimental observations and the theoretical framework that led to the discovery of the electron. It demonstrates an understanding of the historical context and significance of cathode ray experiments in particle physics.
