So I was reading about klystrons which are used as amplifiers, and I've got so many questions!![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
1st of all , what does an amplifier like klystron do? Does it incease the frequency of the input microwave?
What does low power microwave mean? Are they low power because of lw frequency or intensity?
What is the relationship between amplitude and frequency?
Why is velocity modulation is important in klystrons? Can't we just have all electrons with the same velocity for having high frequency microwave and not a wide bandwidth of microwaves?
It seems that I almost learn nothing about waves![Red Face :redface: :redface:](https://www.physicsforums.com/styles/physicsforums/xenforo/smilies/oldschool/redface.gif)
