(i) In a cathode ray tube, the anode accelerates the electrons and also focuses them in a fine energetic beam.
(ii) In a cathode ray tube, electric energy is converted into heat energy and then into light energy.
(iii) Cathode ray tube is used in oscilloscopes, which find their application in physics laboratories.
