EINSTEIN AND THE EMISSION THEORY OF LIGHT

http://www.pitt.edu/~jdnorton/papers/companion.pdf
John Norton: "Einstein could not see how to formulate a fully relativistic electrodynamics merely using his new device of field transformations. So he considered the possibility of modifying Maxwells electrodynamics in order to bring it into accord with an emission theory of light, such as Newton had originally conceived. There was some inevitability in these attempts, as long as he held to classical (Galilean) kinematics. Imagine that some emitter sends out a light beam at c. According to this kinematics, an observer who moves past at v in the opposite direction, will see the emitter moving at v and the light emitted at c+v."

And the frequency the observer will see is f'=(c+v)/L, where L is the wavelength:

Roger Barlow, Professor of Particle Physics: "Moving Observer. Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/(lambda) waves pass a fixed point. A moving point adds another vt/(lambda). So f'=(c+v)/(lambda)."

Einsteinians,

Is f', the frequency the observer sees, compatible with c'=c+v, the variable speed of light predicted by Newton's emission theory of light?

Einsteinians ready to answer the question:
