Question

Klystron valve is used to produce

• A. gamma rays
• B. X-rays
• C. microwaves
• D. infrared waves

Hint:

Remember Klystron for microwave generation in radar and communication. Distinguish wave types: gamma (nuclear), X-rays (high-energy electrons), microwaves (vacuum tubes like Klystron), infrared (heat). Recall frequency ranges: microwaves 300 MHz to 300 GHz.

Answer 1

The Correct Option is C

1. A Klystron is a type of vacuum tube used in high-frequency applications, particularly in microwave technology.
2. It operates on the principle of velocity modulation, where electrons are bunched to amplify signals at microwave frequencies.
3. Klystrons are commonly used in radar systems, particle accelerators, and television broadcasting to generate or amplify microwaves.
4. Gamma rays are produced by nuclear decays, X-rays by electron transitions or bremsstrahlung, and infrared waves by thermal radiation or LEDs.
5. Thus, the Klystron valve specifically produces microwaves, making option (3) correct.
