10th Class Physics Chapter 16 Short Questions with Answers Solved

Question: 1

What are cathode rays? How are cathode rays produced?

Answer: 1

1-10

Cathode Rays: Electron beam produced by elecron gun is also called cathode rays

Nature of Cathode Rays:

From he experiments of deflection of cathode rays by both elecric and magnetic fiedl, it is concluded that cathode rays are neatively charged electrons.

Production of Cathode rays:

For the production of electrons beam, we will examine an experiment performed by J.J. Thomson in discovering the properties of elecrons. for this purpose ,an electron gun is used through which the electrons are produced by the thermionic emission from a ungsten filament heated by 6 V supply as
