what are the properties of cathode rays
The properties of cathode rays are:
i. They travel in straight line and thus cast a shadow of solid things placed in their path.
ii. They are made up of matter/ particles. They have enrgy because of their mass and velocity.
iii. They are made up of negatively charged particles. So, in an electric field they deflect towards anode.
iv. When they strike an object, some of the kinetic energy of cathode rays is transferred to the object causing heating in it.
v. On the surface of glass, the y cause green fluorescence.
vi. They can penetrate through thin metal sheets.
vii. They ionize gases which are present in the medium these rays are travelling in.
viii. The speed with which these rays travel is approximately equal to that of light.
