Question

2. List 3 discoveries from the experiment with his newly discovered cathode rays​

Answer 1

The experiment with Cathode rays revealed the existence of electrons, uncovered the properties of these electrons, including their charge and mass, and showed that electrons are a standard component of all matter.

Step-by-step explanation:

The experiment with Cathode rays led to many significant discoveries in the realm of Physics, particularly related to subatomic particles. Here are three crucial findings:

1. Existence of electrons: Cathode rays consisted of negatively charged particles called electrons. This was the first time subatomic particles were discovered, shaking the then popular belief that atoms were indivisible.
2. Properties of electrons: The experiments revealed that these electrons have properties like charge and mass. J.J. Thomson calculated the charge-to-mass ratio, leading to better understanding about atomic structure.
3. Universality of electrons: The same kind of rays were produced regardless of the type of gas in the tube or the material of the electrodes, indicating that electrons are a fundamental, universal component of matter.
