Q. In a oscillator, the RF wave travels along the helix from the collector towards the electron gun.

  • (A) interaction oscillator
  • (B) backward wave oscillator
  • (C) magnetrons
  • (D) none o the mentioned
💬 Discuss
✅ Correct Answer: (B) backward wave oscillator
Explanation: in a backward wave oscillator, the rf wave travels along the helix from the collector towards the electron gun. thus the signal for oscillation is provided by the bunched electron beam itself and oscillation occurs.
