They cause a greenish-yellow fluorescence on a soda-glass screen. They travel from the anode to the cathode. They travel from the cathode to the anode. How do cathode rays differ from anode rays? These rays were named positive rays or anode rays. He called these rays as canal rays since these rays passed through the holes or canals in the cathode. In discharge tube experiment, Goldstein noticed another set of rays travelling in a direction opposite to that of the cathode rays i.e., from anode towards cathode, when perforated cathode was used in the discharge tube. Why were anode rays also called as 'canal rays'? When a beam of cathode rays is made to fall upon hard metallic targets like tungsten, X-rays are produced. Question 5Ĭathode rays are negatively charged as they are made of negatively charged particles.Īnode rays are positively charged as they are made of positively charged particles. What are the cathode rays? How are these rays formed?Ĭathode rays are a stream of electrons that travel from the negatively charged electrode (the cathode) to the positively charged electrode (the anode) in a discharge tube.įormation of cathode rays - When a high voltage (10,000 volts) charge from an induction coil is applied to tubes filled with gases at very low pressure (0.01 mm of Hg), the gases become good conductors of electricity and begin to flow from cathode to anode in the form of rays which are called cathode rays. ![]() It is formed by removing 2 electrons from helium atom.
