Question

explain Rutherford cathod ray experiment

Answer 1

Rutherford projected alpha particles towards a thin gold foil,-in the path of the rays; He saw that most of the alpha particles when straight through the foil but some were deflected slightly and some by large angle.He then gave a conclusion that an atom on a whole is relatively empty but consists of a concentrated positive mass in the center which lead to be deflect by the alpha particles. This resulted in the discovery of the center positive region -atomic nucleus was initiated 

Answer 2

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.
