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.

How do negatively charged plates affect the path of cathode rays?
negatively charged plates affect the path of cathode rays by repealing the cathode rays.
The behavior of cathode rays in a glass tube containing gas at low pressure led scientists to conclude that the rays were composed of?
Were composed of no charge particles .
What did JJ Thomson's cathode-ray tube experiment show?
Thompson observed that these rays are negatively electrically charged.
Why are anode rays called canal rays?
Anode rays are positively charged .so they are bend towards perforated cathode which is negatively charged and pass through them.since they have passed through canals or holes by producing fluorescence. Therefore they are known as canal rays.
What evidence convinced Thomson that cathode rays consist of negatively charged particles?
In a series of experiments in the 1890's, J.J.Thompson showed that cathode rays, or electrons, are deflected by an electric field, they are bent by a magnetic field, and that their charge to mass ratio is about 1/2000th of that of the proton. Light does not have any of these properties.
How do negatively charged plates affect the path of cathode rays?
negatively charged plates affect the path of cathode rays by repealing the cathode rays.
Why are cathode rays deflected away from a negatively charged plate?
Alpha Rays are attracted to a negatively charged plate because they consist of positively charged particles.
How do charged plates affect the plates of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
What is the charge of the cathode tube particles?
Cathode rays are high speed electrons. So they are negatively charged.
What particle was observed in the cathode rays?
The negatively charged particle called electron.
How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
What is the charge of the particle in cathode rays?
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
The behavior of cathode rays in a glass tube containing gas at low pressure led scientists to conclude that the rays were composed of?
Were composed of no charge particles .
How are cathode charged?
negatively charged
Why did j.j reason the electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes. Cathode rays, otherwise known as electrons, are repelled by a negative charge, and attracted to a positive charge.
