Basically the thermionic rays are fast moving electrons. They originate in the region having an excess of electrons. So originate from the cathode.
Cathode rays are produced when the metal cathode has a high voltage applied to it - this has the effect of "boiling" the electrons off the cathode's surface producing cathode rays, and so cathode rays can be seen as a stream of electrons i.e. negatively charged particles.AnswerElectrons are released from the surface of a cathode through thermionic emission. This is achieved by a heaterlocated at the cathode, and not due to a high voltage. The function of the high voltage (between the cathode and an anode placed closer to the screen) is to attract these electrons towards the screen of the CRT. So a 'cathode ray' is simply a beam of electrons which, of course, are negatively charged.
negatively charged plates affect the path of cathode rays by repealing the cathode rays.
A modern day name for cathode rays is an electrons.
Anode Rays are called the canal rays as the cathode used is perforated and the anode rays pass through the holes or canals of The cathode opposite to the anode.
Cathode rays are beams of electrons.

Cathode rays are the emission of free electrons form the negative pole of an electric circuit. To get this to happen you need to warm the cathode and place it in a vacuum tube with a high voltage across it. The electron then jump form the cathode and fly across the empty tube to the anode (positive end). They may be bent by magnetic fields in flight.
Cathode rays are electrons.
Cathode rays are electrons.
cathode rays can emit electrons anode can collect them
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
Cathode rays are electron beams.
The cathode ray is a stream of electrons.
negatively charged plates affect the path of cathode rays by repealing the cathode rays.
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
experiments with cathode rays lead to the discovery of the Electron.
they aren't. cathode rays are charged electrons, light is uncharged photons.
