All but two of my cars are Fords, all but two of my cars are Toyotas and all but two of my cars are Hondas. How many cars do I have. The obvious answer is three. I'm arguing with some folks that are claiming two is an acceptable answer and they are using the rationale that it is fine to...

Okay, let me see if I have this straight: The speed of light is constant. When one makes the claim that light is slower, in, say water, than in a vacuum, it's because it only seems slower because the light photons did not end up at point B as fast as it would have in a vacuum because it...

I'm not getting what you're saying here. It sounds like you're saying light takes longer to get from point A to point B because it has bounced off of molecules and hasn't gone in a straight line. If that's what you're saying, the photons themselves have still gone at a constant speed, no?

Does the speed of light slow down due to air resistance? I often hear about how the speed of light is constant in a vacuum, and I'm assuming it has something to due with it being different in air due to air resistance. If so, why is this? Since light has no mass, shouldn't air not have an affect...
