Answer» Discharge tube experiment explains the particles of matter coming with glow is cathode rays having negative charge electrons.Explanation:In discharge tube experiment, at low pressure and at very high VOLTAGE, an electric current is passed. Due to passage of electric current, a STREAM of rays is passed in the tube originating from cathode. These rays are called "CATHODE RAYS".PROPERTIES OF CATHODE RAYS :These rays ORIGINATE from cathode. Cathode rays travel in straight line. Cathode rays CARRY negative charge. Cathode rays are deflected by electric field. Cathode rays are deflected by magnetic field. These rays consist of material particles. The ratio e / m of these particles was 1.76 x 108 col / GM. Cathode rays consist of "electron". The rays, upon striking glass or certain other materials, cause them to glow |
