Hi,
the theory of relativities second postulate is:-
The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light
A physical process occurs when a photon is being emitted and this process takes place at speed of light. If you are moving towards the incoming photon one would expect the apparent speed of the photon, before allowing for your own speed, to be greater than c.
Am I right in thinking that the second postulate says that the apparent speed is still c?
I think it does - how can this be?
Thanks
