I'm sorry, I don't understand what you are asking. Could you elaborate your question a bit more?

The speed of light in a vacuum is always c. Michelson and Morley erroneously thought that light would travel at c+v if it was moving in the same direction as the aether (which presumably travels at v), and c-v when moving in the opposite direction as the aether.
