Answer to Question 1

An electromagnetic wave can be described by: . Thus, the longer the wavelength, , of an electromagnetic wave, the lower must be its frequency, , and vice versa.

Answer to Question 2

For simplicity, consider a two component system linked by a positive and a negative coupling. If one component is perturbed, the sign of that perturbation is retained through the positive coupling but reversed through the negative coupling. Thus, overall the negative feedback loop reverses the sign of the initial perturbation, tending to restore the system to its initial state.
