We always consider light speed as v=lambda/T but for a moment let's suppose that light would travel all around the function, following the whole curve. In this case its speed would be at least doubled (should not be difficult to calculate it) and it will constantly change depending on the frequence. So i'm not talking about the speed of light as v=lambda/T but how much space light really travel on. if the classical rule is right, for absurde, it means that a photon, following the function (y=sen...etc) must absolutly maintain his horizzontal speed constant, so, this means, that in a wave the photon would accelerate a lot when the curve begins to be almost vertical, then when it returns almost orizzontal (the top or the bottom) it would decrease his speed relative to the horizontal travelling....and this is impossible for the standard theory (standard for me is hight school physics, what i am doing); as the bible says, c is constant. (i know i semplified about waves photons and functions...probably are the same thing) So should not be considered c speed as its entire track, the whole function followed?
