Electrons, accelerated by electric fields and focused by magnetic fields to scan across a phosphor-coated screen.
Electrons.
Yes. Cathode rays, otherwise known as electrons, are repelled by a negative charge, and attracted to a positive charge.
Cathode rays are a stream of electrons originating from cathode and moving to an anode, when high voltage electric potential is applied to the electrodes sealed in a glass tube containing gas...
A stream of electrons emitted by the cathode in electrical discharge tubes. One of the electrons that is emitted in a stream from a cathode-ray tube.
