- special relativity light paradox

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?
