How would that be possible? The speed of ANY wave - not only EM waves - must always be the product of wavelength * frequency. This is not advanced math, but simple geometrical reasoning. You can't circumvent that. For example, if light goes at 300,000 km/sec, and the frequency is one second, you'll have one wave crest every 300,000 km, since that is the distance the previous wave crest advanced in one second.
Nor have countless experiments produced any evidence that light goes at any speed but "c".
>If anyone can think of a way to test that, it would be pretty good proof.
It should be possible, in principle, to shine a laser from the moon, or perhaps from a spacecraft further away, and measure any change in frequency. But I guess that first there would have to be a sound theory to justify such an experiment.
