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.
· Travel in straight lines: They cast a shadow of the objects placed in their way.
· Produce mechanical effect: A paddle wheel placed in their path starts rotating.
· Rays are positively charged: Anode rays are deflected towards the negative plate of an electric field.
· The nature of the anode rays depends upon the gas taken in the discharge tube. Different gases give different types of positive rays, which contain particles having different masses and different charges. Therefore the (e/m) ratio is not constant for positive ray particles obtained from different gases.
the properties of cathode rays are:
1)it helps in separating metals from a fluid mixture
2)it helps in separating non metals from metals
3)it helps in the process of galvanisation
4)it helps in curing many major diseases
5)it can be used in the process of electrolysing
cathode rays are negatively charged.
cathode rays travel in straight line if not in
magnetic field.
cathode rays produce heating effect.
cathode rays are affected by electric and magnetic field.
Cathode rays are composed of electrons that have emitted from gases inside a cathode ray tube. Cathode rays were determined to be electrons by placing them under the influence of a magnetic field. The ray responded and was attracted to a positive plate.
Properties of positive rays:
*Anode rays travels in a straight line.
*It has positive charge.
*They consists of material particles.
*These particles which have a mass 1836 times that of the electrons are known as protons
The cathode ray can be steered by a magnetic (or electric) field, and hence their mass may be deduced.
Electrons
The cathode ray is a stream of electrons.
Ddischarge tube led to the discovery of Cathode rays (electrons) and Positive rays (protons) so this discovery of cathode rays and positive rays can be considered as conse quences of discharge tube.
There are no rays assign as anode rays (cathode rays are there in a discharge tube) but during discharge tube experiment positive rays are observed which are generated by decomposition of gaseous molecules present in the tube. X-rays are produced by striking of cathode rays with anode so x-rays may be called as anode rays.
English Physicist J.J. Thomson (1856-1940)
Electrons.
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.
negatively charged plates affect the path of cathode rays by repealing the cathode rays.
The cathode ray is a stream of electrons.
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.
