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 at low pressure.
Cathode rays are stream of negativley charged electrons getting detached right from neutral molecues due to high voltage and driven right from cathode to anode.

Which scientist discovered that cathode rays are made up of negatively charged particles?
J.J. Thomson discovered that cathode rays are made up of negatively charged particles. He conducted experiments using cathode ray tubes and found that the rays were deflected by electric and magnetic fields in a manner consistent with the presence of negatively charged particles.
Why did Thomson see cathode rays with every element?
Thomson observed cathode rays with every element because cathode rays are composed of electrons, which are fundamental particles present in all atoms regardless of the element. When a high voltage is applied in a vacuum tube, electrons are emitted from the cathode and accelerate toward the anode, creating cathode rays. This universal presence of electrons in all elements allowed Thomson to consistently detect cathode rays across different materials. His experiments demonstrated that these rays were not dependent on the type of gas or metal used in the cathode.
Is cathode rays are material particles?
Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.
Why do cathode rays produce sharp shadow of object placed in their path?
Cathode rays produce a sharp shadow of an object because they travel in straight lines and can only pass through openings in obstacles. When an object is placed in the path of cathode rays, the rays are blocked by the object, creating a distinct shadow where the rays are unable to pass through. This phenomenon is due to the wave-particle duality of cathode rays.
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes, cathode rays are deflected towards a positively charged plate in an electric field. The negatively charged particles in the cathode rays are attracted to the positive plate, causing the deflection.
Cathode rays were found to be made of protons.?
Cathode rays are electrons.
How are x rays made?
X- RAY made from cathode ray osloscope
Cathode rays were shown to be a stream of?
Cathode rays are electrons.
What are the uses of Cathode Rays and Anode Rays?
cathode rays can emit electrons anode can collect them
What is the modern day name for cathode rays?
Cathode rays are electron beams.
What is modern name for cathode rays?
A modern day name for cathode rays is an electrons.
In cathode ray tube cathode and anode rays travel opposite to each other but they are not neutralized. why?
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
Thomson made his discovery about the atom during an experiment using?
Cathode Rays
Who said Cathode rays are made up of negayively charged particles?
J.J.Thompson
What did experiments with cathode rays lead to the discovery of what?
experiments with cathode rays lead to the discovery of the Electron.
What is the charge of the particle in cathode rays?
The charge of the particle in cathode rays is negative. This was determined by J.J. Thomson through his experiments with cathode ray tubes in the late 19th century, which led to the discovery of the electron.
Is cathrone rays steams of electron?
yes, cathode rays are streams of electrons
