Answer» (a) The beam ofrayswhich travel in a direction away fromanodetowardscathodewhen a gas taken in a discharge tube is subjected to the action of high voltage under low pressure are known ascanal rays. It is also calledanode rays. E.Goldstein discovered them. Charge son canal rays is positive and mass is one unit. (b) Electrons are negatively charged and mass approximately is 1/2000 that of canal rays. what are cathode Ray's ?who discovered it? |
