The name of the equipment that John Thomson did the experiments was cathode ray tube.
Explanation:
- John Thomson's experiments was to study the nature of electric discharges in a cathode ray tube. They are sealed glass tubes and the inside of the tube was maintained in high vacuum.
- John Thomson's cathode ray tube experiments were significant because he proved that all the atoms contain, electrons. Electrons are the negatively charged subatomic particles.
- Cathode ray is the particle beam that contains this negatively charged electrons.
