problem 5: List two advantages of using Microwave frequency over low frequency?

problem 6: Define the term Transit time effect.

problem 7: What are the basic difference between Magnetron and TWT?

problem 8: Why at microwave frequency we talk of traveling waves with related powers rather than currents and voltages?
