Write the properties of cathode rays.

Explanation

Cathode rays possess energy and momentum and travel in a straight line with high speed of the order of `10^(7)ms^(-1)`
It can be deflected by application of electric and magnetic fields.
• When the cathode rays are allowed to fall on matter, they produce heat.
• They affect the photographic plates and also produce fluorescence when they fall on certain crystals and minerals.
• When the cathode rays fall on a material of high atomic weight, x-rays are produced. .
Cathode rays ionize the gas through which they pass.
• The speed of cathode rays is up to `((1)/(10))^(th)`of the speed of light
