Final answer:

Cathode rays are deflected by electric fields, consist of electrons, and are produced under specific conditions.


Explanation:

The effect of an electric field on cathode rays: Cathode rays are deflected towards the positive electrode, indicating they are negatively charged.

Sub-atomic particles in cathode rays: Cathode rays consist of electrons.

Conditions for cathode ray production: Cathode rays are produced under vacuum and when a high voltage is applied across electrodes in a cathode ray tube.
