The formula

(frequency) = (speed of light)/(wavelength)

can be combined with one of the following axioms:

Axiom 1: The speed of light is invariable.

Axiom 2: The wavelength of light is invariable.

Axiom 1 killed physics - this branch of science leads a zombie life now. Axiom 2 will resurrect it (if it's not too late). Today's zombie science, entirely based on the false constant-speed-of-light axiom, will be destroyed:
