Posts: 2,856 I know like your X4 idea, but I have asked you to start posting in a new thread in the Lounge. Please stop making posts in this thread about X4. I have found very little to use in terms of predictions or structure. There is nothing about X4 to warrant calling it a "Common Misconception." -Dan __________________ Do not meddle in the affairs of dragons for you are crunchy and taste good with ketchup.

Sorry about not getting back to you (neila). I was trying to come up with a particle representation of your question, as well as a version including a massive particle. I couldn't figure that one out. But, as the question involves photons anyway, I can work with it.

The answer to your question is that the velocity component in the x direction is equal to c. This is from Huygen's principle.
