Question

High voltage A depiction of a famous scientific experiment is given. Consider how the beam changes when the magnet is off compared to when the magnet is on. Evacuated glass tube Electrically charged plates What type of beam was used in this experiment?

a) alpha particles
b) neutron beam
c) proton beam
d) cathode ray

Answer 1

The type of beam used in this experiment is a cathode ray.

Step-by-step explanation:

The beam used in the famous scientific experiment described is called the cathode ray. In this experiment, a cathode-ray tube is used to produce a narrow beam of electrons that pass through charging plates connected to a high-voltage power supply. The beam is bent when the magnet is on due to the opposing forces of the electric and magnetic fields on the electrons.
