$Q:- What \: are \: cathode \: rays \: and \: what \: is \: its \: nature? \\ </p><p>Ans:- If \: an \: electric \: current \: of \: high \: voltage \: \\ is \: passed \: through \: an \: elementary \: gas \: filled \: in \: \\ a \: glass \: tube \: and \: maintained \: at \: very \: low \: \\ pressure \: ( a \: pressure \: of \: 0.01 \: mm \: of \: mercury), \: \\ bluish \: rays \: of \: light \: are \: emitted \: from \: the \: \\ cathode \: and \: move \: towards \: the \: anode. \\ </p><p>These \: rays \: are \: called \: Cathode \: Rays. \: \\ The \: cathode \: rays \: are \: made \: up \: of \: negatively \: \\ charged \: particles \: called \: Electrons \\ = > JJ \: Thomson \: showed \: this$
