Question

what are the properties of cathode ray ???​

Answer 1

Answer:

They travel in straight line from cathode and cast shadows of metallic objects placed in their path.

They cause mechanical motion of small pin-wheel placed in their path. ...

They produce fluorescence when they strike the glass wall of the discharge tube.

_____________________________________

The important properties of cathode rays were studied by J.J Thomson and co-workers based upon certain experiments these are described as follows in the given attachments.

properties of cathode rays:-

1. cathode rays travel in straight line:when a solid object is placed in the path of cathode rays, its shadow is noticed immediately behind it .This shows that the cathode rays travel in straight line.
2. cathode rays are made up of material particles: if a light paddle wheel made from mica and mounted on a axis is placed in the path of the cathode rays , it starts rotating . This shows that the cathode rays consist of material particles .
3. cathode rays consists of negatively charged particles : when electric field is applied on the cathode rays with the help of a pair of metal plates, these are found to be deflected towards the positive plate , indicating the presence of negative.
