In 1865 Maxwell wrote down an equation to describe these electromagnetic waves. The equation showed that different wavelengths of light appear to us as different colours. But more importantly, it revealed that there was a whole spectrum of invisible waves, of which the light we can see was only a small part.

Hence all the Maxwell equations are correct in terms of Einstein’s special theory of relativity.
