 Experiment 6 -- Medium Emission of a Moving Charge

- When a charge is at rest, medium is emitted by it and flows outward in the same manner in all directions. But, when the charge is in motion at constant velocity, v, the flow forward is emitted at speed [c - v] and rearward at [c + v] per experiment #2.

- There can be only one frequency, f, in the [1 - Cosine(2π∙f∙t)] form oscillation of the emitted flow regardless of whether it is directed forward, rearward or sideward. Therefore, to obtain the slower speed, [c - v], emitted forward the wavelength forward, l_fwd , must be shorter so that the speed at which the flow is emitted, = f∙l_fwd , will be slower.

- The case is analogous rearward where l_rwd is longer in order for the speed, [c + v], to be greater.

 In all directions from the moving charge, including any that are partially sideward plus partially forward or rearward, the speed of emission and the wavelength emitted will be the resultant of the sideward plus forward or rearward components of a ray in that direction.

 Experiment 7 -- Medium Flow Outward From a Moving Charge

- The absolute rate of flow outward of the emitted medium must be at speed c. Forward that comes about because the forward speed of the charge, v, adds to the forward speed at which the medium is emitted, [c - v], resulting in the medium flowing at the speed of the sum, speed = v + [c - v] = c.

- That speed increase raises the [1 - Cosine(2π∙f∙t)] form oscillation frequency (per the Doppler Effect). Thus forward medium flow speed is c = f_fwd∙l_fwd .

- Analogously rearward the speed of medium flow is at c = f_rwd∙l_rwd .

 In all directions from the moving charge, including any that are partially sideward plus partially forward or rearward, the speed of flow will be c and the frequency and wavelength of the flow will be the resultant of the sideward plus forward or rearward components of a ray in that direction.

 Experiment 8 -- Magnetic Field

- A charge at rest exhibits the electrostatic effect but not the magnetic effect. That charge has a spherically uniform pattern of [1 - Cosine(2π∙f∙t)] form oscillatory medium emission and flow outward.

- A charge in motion exhibits the magnetic effect in addition to the electrostatic effect. That charge has a pattern of emission and outward flow of medium that is cylindrically symmetrical about the direction of motion but that varies in wavelength and frequency from f_fwd∙l_fwd forward to f_rwd∙l_rwd rearward.

 The electrostatic [Coulomb's Law] effect is known to be due to charge location. The magnetic [Ampere's Law] effect is known to be due to charge motion. Clearly, then, the electrostatic effect is due to the spherically uniform medium flow from the charge and the magnetic effect is due to the change in shape of that medium flow pattern caused by the charge's motion.

 Experiment 9 -- Electro-magnetic Field

- There is a continuous emission of medium in [1 - Cosine(2π∙f∙t)] oscillatory form from each charge, which medium flows outward, away, forever. Constant velocity motion of a charge produces a change in the frequency and wavelength of that medium flow. The amount of the change varies according to the direction of each ray of medium flow away from the charge, whether forward or rearward or in between, and also depends on v, the charge velocity.

- Changes in the [constant in the above discussion] velocity of the charge cause corresponding further changes in the medium's oscillatory form as successive increments of medium are emitted from and flow outward from the charge. Earlier increments so changed propagate on outward away from the charge, forever, at c. The stream of outward flowing medium carries a history of the motions of the source charge.

- Electro-magnetic field is caused by acceleration / deceleration of charge, that is by changes in the charge velocity. Therefore:

 The changing electric and magnetic fields of electro-magnetic field actually are form changes imprinted onto the outgoing medium flow and carried passively with it [analogous to modulation of a carrier wave in radio communications].

 Because all medium flow is spherically outward in all directions from its source charge, changes in it, caused by changes in the source charge velocity, propagate outward in all directions. Those medium flow changes are the changing electric and changing magnetic fields of electro-magnetic field.

It is not the speed of light which is the fundamental constant, c, light being a mere modulatory imprint on medium flow. It is the speed of medium flow which is the fundamental constant, c.
