Relativity

Does anyone on the forum know the predictions of special relativity? I’ve asked physicists to explain the following simple paradox but they don’t want to know, so are any physics oriented engineers prepared to discuss it?


How can a photon have a frequency? Anything moving at the speed of light is predicted to have a zero time rate, e.g. the frequency of a ticking clock would be zero. So no aspect of the light should change along its path - in the same way that no aspect of the moving clock would change.

If special relativity doesn’t apply to light, i.e. a Lorentz transformation is not applied to give light zero frequency, then it cannot be used to multiply a photon's zero rest mass by infinity to give it mass. So photons would have no energy or frequency or even existence. Does the theory apply to light or not?
