How are the cathode rays produced?

Best Answers

CATHODE RAYS. The electrons are produced at the cathode by thermionic emission and are accelerated towards the screen by the anode which is connected to the terminal of the extra high tension battery. The thermionic emission is the process whereby metal surfaces emit electrons when heated. read more

Cathode rays are just a beam of electron observed in vaccum tube. when the dicharge tube or evacuated glass tube is facilitated with 2 electrode and with high voltage, due to emmission of electron from and travelling in perpendicular to cathode,glass opposite of negative electrode(ie cathode) is observed to glow. read more

Cathode rays are produced when a high voltage is applied between two terminals in a low-pressure environment. In this low pressure, it is easier for the electrons to flow from the negative terminal and form a beam of negatively charged electrons, which can be bent, or deflected, by magnetic fields and electric fields. read more

When a cathode ray deflection tube is connected as shown in Figure, the cathode rays are seen deflected towards the positive plate and away from the negative plate. The path of the cathode rays in an electric field is the shape of a parabola as shown in Figure. read more
