Atoms are made up of three subatomic particles electrons, Protons and neutrons. Electron has negative charge, proton has positive charge, whereas neutron has no charge, it is neutral. Protons and neutrons are present in a small nucleus at the centre of the atom. Electrons are outside the nucleus. The atoms of different elements differ in the number of electrons, protons and neutrons.<\/p>\n

Aim:<\/strong> To study the properties of cathode rays. Observations:<\/strong><\/p>\n Discussion:<\/strong><\/p>\n The pressure in the tube is decreased, it was observed that in addition to cathode rays, a new kind of rays are also found which came through the perforations (holes) of the cathode. These rays travelled in opposite direction of the cathode rays and passed through the holes of the cathode and struck the other end of the discharge tube. When these radiations struck the end of the tube P, the fluorescent radiations were also produced. These rays were called canal rays because they are passed through the holes or canals in the cathode. These were also called anode rays because they move from the anode. It was found that the anode rays consist of positively charged particles. Therefore, these rays were also called positive rays.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" How are the Anode and Cathode rays Produced?

\n(a) Surface area of the metal<\/strong>
\nThe larger the surface area, the more the number of electrons emitted.
\n(b) Temperature of the metal<\/strong>
\nThe higher the temperature, the more the number of electrons which will gain enough energy to escape from the metal surface.
\n(c) Type of metal<\/strong>
\nDifferent types of metal requires different amounts of energy for the electrons to escape.
\n(d) Nature of the metal surface<\/strong>
\nWhen the metal surface is coated with metal oxide, electrons can be emitted at a lower temperature.<\/li>\n<\/ol>\nHow are the cathode rays produced?<\/strong><\/h2>\n

\n(a) These rays originate from the cathode; therefore they are beams of negatively charged particles called electrons.
\n(b) They travel in straight lines and cast sharp shadows.
\n(c) They travel at high speed and have kinetic energy and momentum.
\n(d) They can do work and therefore can generate fluorescence when they hit the fluorescent screen.
\n(e) They are deflected by magnetic fields and electric fields.<\/li>\n<\/ul>\nProperties of Cathode Rays Experiment<\/b><\/strong><\/span><\/h2>\n
