Which one of the following statements regarding cathode rays is not correct?

Options

  1. ACathode ray particles are electrons.
  2. BCathode ray particles start from anode and move towards cathode.
  3. CIn the absence of electrical and magnetic fields, cathode rays travel in straight lines.
  4. DTelevision picture tubes are cathode ray tubes.

Correct answer

B. Cathode ray particles start from anode and move towards cathode.

Step-by-step solution

Cathode are produced by the negative electrode, or cathode, in an evacuated tube, and travel towards the anode. They travel in straight lines and cast sharp shadows. They have energy and can do work. They are deflected by electric and magnetic fields and have a negative charge.
