J.j thompson cathode ray experiment6/16/2023 Electrons are focused by the electron gun: The electron gun consists of a series of anodes and lenses that help to shape and focus the electron beam.As the electrons are accelerated toward the anode, they gain kinetic energy. Electrons are accelerated by the anode: The anode is a positively charged electrode that attracts the negatively charged electrons emitted by the cathode.These electrons are negatively charged and are attracted to the positively charged anode. Electrons are emitted from the cathode: When a voltage is applied to the cathode, it heats up and emits electrons.The working of a cathode ray tube (CRT) involves several steps, as follows: ![]() These components work together to produce the characteristic electron beam and display images on the fluorescent screen. ![]() This prevents the electrons from colliding with gas molecules in the tube and disrupting the electron beam. The tube is evacuated to a very low pressure, typically around $10^$ torr. Advertisements A Cathode ray tube, source: Javatpoint
