\nThe statement that is NOT correct regarding cathode rays is B) Cathode ray particles start from anode and move towards cathode.
\n<\/section>\n
\nCathode rays are streams of negatively charged particles (electrons). In a discharge tube, these electrons are emitted from the cathode (the negative electrode) and are accelerated towards the anode (the positive electrode) by the electric field between them. Therefore, cathode rays move from the cathode towards the anode, not the other way around.
\n<\/section>\n
\nStatement A is correct: Cathode ray particles are indeed electrons. Statement C is correct: In the absence of external electric or magnetic fields, cathode rays travel in straight lines. Statement D is correct: Older style Television picture tubes (CRTs – Cathode Ray Tubes) and computer monitors utilized controlled beams of cathode rays to create images on a phosphorescent screen.
