Is that not correct? | |

| Dec 12, 2014 at 19:41 | comment | added | Jim | This is similar to saying that the wavelength of all light goes to infinity and therefore there is no light; it's all darkness. But as the difference between electricity and magnetism is due to relativity (simplistically speaking), then it is not certain that light would need magnetic fields if the speed were infinite. Or rather, the fields might all be interpreted as electric even if they correspond to magnetic fields in the field strength tensor | |
