Cathode rays are deflected towards__________.
A. Positive electrode
B. Negative electrode
C. Both electrode
D. None of these

Hint: When cathode rays hit the glass or other materials, they yield green fluorescence. They are bounced from their straight path in the direction of the positive plate of the electric field, every time an electric field or magnetic field is operated on the cathode rays. This shows that cathode rays are negatively charged particles. As there is a pull between electrons and a positive electrode, cathode rays are deflected in the direction of the positive electrode

Complete step by step solution:
Cathode rays arise from the cathode as the cathode is negatively charged. Thus, these rays hit and ionize the gas sample existing inside the container. Their properties are not influenced by the electrodes and the gas used in the vacuum tube. The speed of cathode rays is relaxed than that of light. The objects that are stricken by cathode rays get heated. Cathode rays are proficient in piercing through thin metal plates. Phosphors usually glow when cathode rays fall on them. Gas gets ionized by the cathode rays. Cathode rays are a hundred and eighty times lighter than hydrogen elements. The electrons which are emitted from gas ionization travel in the direction of the anode. Electrons are kind of atomic particles that are negatively charged. The opposite nature of charges makes them always attract each other. These rays are electrons that are created from the gas ionization inside the tube. They move in a straight line and they can produce sharp shadows. They are formed at the cathode and move to the anode in a vacuum tube, Hence option (A) is correct.

Note:
Cathode rays are also called electron beams or an e-beam. These are streams of electrons detected in the vacuum tubes. The images in television are generated by a focused beam of electrons deflected by electric and also magnetic fields in cathode ray tubes.
