explaination of discharged tube of cathode
Answers
hey mate here's your answer
discharged tube of cathode is (1) cathode is a ray it travels in straight lines and thus cast shadows of objects placed in their path (2) cathode rays possess material particles because they can rotate a light padd wheel placed in thier path so they are deflected towards positive plate thus showing that thee are negatively charged particles known s electrons they ionise gas through which they pass they are deflected by magnetic fields the nature of cathode rays is independent of the materials of a
cathode hence they are common constituents of all matter they are penetrate through thin metallic sheet they can produce x ray the mass of a cathode ray particles is very very small as compared to tell mass of the atom from which it is formed .
I hope it will helps you
