Cathode rays experiment explanation which rays
Answers
Explanation:
cathode ray experiment was done by J J Thomson. in this experiment he discovered the cathod rays in long tube and putting two electorads cathode and anod. then he passed out high electricity through it. and a light emerge from the tube. by the the cathode electorad . and then put two plates on the tube one with positive charge and other negative charge. and then the light turned on to positive plate. J J Thomson called these negative rays as cathode ray.

Answer:
Explanation:
The stream of electrons in cathode ray tube constitutes the cathode rays. Electrons are emitted by hot filament by the process of thermionic emission. These electrons pass through controlling and focusing device . They are accelerated by applying appropriate voltage between cathode and anode and finally made incident on a flourascent screen after passing through cross electric and magnetic fields.
