A physical process can be represented by Feynman diagrams, each with a complex amplitude.(adsbygoogle = window.adsbygoogle || []).push({});

Squaring the sum of these amplitudes gives the rate at which a process occurs.

Since a rate can be a frequency,doesn't this imply that before the sum of amplitudes is squared, we are dealing with the square root of a frequency?

Is a complex amplitude just the square root of a frequency,and how can it

be when a frequency is a real number?
