MCQ
A modified discharge tube is used as a $.......$:
- ACathode ray oscilloscope
- BFluorescent tube
- C$X-$ray tube
- ✓All the above
✓
Answer
Correct option: D.
All the above
A discharge tube is a tube containing charged electrodes and filled with a gas in which ionization is induced by an electric filed. $X-$ray tube, fluroscent tube and cathode rays oscilloscope can be used as a modified discharge tube in which these tubes contain charged electrodes and filled with a gas.
